For example, CHCl3 (chloroform) is trichloromethane. Now see the four parts ( prefix, word root, bond and functional group) separately. 2-hydroxypropane-1,2,3-tricarboxylic acid, "IUPAC nomenclature of organic chemistry", Learn how and when to remove this template message, International Union of Pure and Applied Chemistry, IUPAC nomenclature of inorganic chemistry, Functional group § Table of common functional groups, International Union of Biochemistry and Molecular Biology, "Table 28(a): Carboxylic acids and related group". Ideally, every possible organic compound should have a name from which an unambiguous structural formula can be created. Simple cations formed by adding a hydron to a hydride of a halogen, chalcogen or pnictogen are named by adding the suffix "-onium" to the element's root: H4N+ is ammonium, H3O+ is oxonium, and H2F+ is fluoronium. padding-left:5px; The prefix form is both "carbamoyl-" and "amido-".e.g. border: 1px black dashed; First, it can refer to any process used to make ethanol unfit for consumption (denatured alcohol). In Haloalkanes and Haloarenes (R-X), Halogen functional groups are prefixed with the bonding position and take the form of fluoro-, chloro-, bromo-, iodo-, etc., depending on the halogen. Simple cis and trans isomers may be indicated with a prefixed cis- or trans-: cis-but-2-ene, trans-but-2-ene. They are combined to create, 4,8-diethyl. If the CH 3 groups in dimethylbenzene, whose common name is xylene, are adjacent to each other, the compound is commonly called ortho-xylene, abbreviated o-xylene. Learn vocabulary, terms, and more with flashcards, games, and other study tools. I don't know about Kevin but here's the correct answer: It represents a substituent group derived from an alkane. This clue was last seen on June 5 2019 on New York Times’s Crossword. ≡ The parent hydrocarbon chain has 23 carbons. It is also noteworthy that if there is a functional group suffix and a substituent, the functional group suffix gets the lowest possible number. If higher precedence functional groups are present (see order of precedence, below), the prefix "hydroxy" is used with the bonding position: CH3CHOHCOOH is 2-hydroxypropanoic acid. In case something is wrong or missing you are kindly requested to leave a message below and one of our staff members will be more than happy to help you out. For example, the three isomers of xylene CH3C6H4CH3, commonly the ortho-, meta-, and para- forms, are 1,2-dimethylbenzene, 1,3-dimethylbenzene, and 1,4-dimethylbenzene. 2 If there are multiple side-branches of the same size alkyl group, their positions are separated by commas and the group prefixed with di-, tri-, tetra-, etc., depending on the number of branches. If there are multiple functional groups of the same type, either prefixed or suffixed, the position numbers are ordered numerically (thus ethane-1,2-diol, not ethane-2,1-diol.) However, many organic cations are obtained by substituting another element or some functional group for a hydrogen. If more than one functional group is present, the one with. On this page you may find the answer for LA Times Daily Crossword clue "Chemistry suffix" published on June 5 2019. border:thin If the carbon in the carbonyl group cannot be included in the attached chain (for instance in the case of cyclic aldehydes), the prefix "formyl-" or the suffix "-carbaldehyde" is used: C6H11CHO is cyclohexanecarbaldehyde. "ates" and "ites" always contain oxygen. In case something is wrong or missing kindly let us … Naming Aldehydes. The di- and tri- have been used just to show their usage. (Do not enter the full name, but include additional words that may follow the suffix.) The rest are named with a Greek numeric prefix, with the exceptions of nonane which has a Latin prefix, and undecane and tridecane which have mixed-language prefixes. If the CH 3 groups in dimethylbenzene, whose common name is xylene, are adjacent to each other, the compound is commonly called ortho-xylene, abbreviated o-xylene. In general, carboxylic acids are named with the suffix -oic acid (etymologically a back-formation from benzoic acid). Hydron is a generic term for hydrogen cation; protons, deuterons and tritons are all hydrons. Has the lowest-numbered locants for prefixes. The R-CO-O part is then named as a separate word based on the carboxylic acid name, with the ending changed from -oic acid to -oate. IUPAC names can sometimes be simpler than older names, as with ethanol, instead of ethyl alcohol. The Hydrons are not found in heavier isotopes, however. eg. CH3CH(CH3)CH2NH(CH3) is N,2-dimethylpropanamine. Aldehydes (R-CHO) take the suffix "-al". The side chains are grouped like this: 12-butyl-4,8-diethyl. Acyl groups are named by stripping the -ic acid of the corresponding carboxylic acid and replacing it with -yl. The suffix for alkenes can go in front of other suffixes. As a general rule an "ide" suffix indicates an element. Please find below the Chemical suffixes answer and solution which is part of Daily Themed Crossword November 28 2019 Answers.Many other players have had difficulties with Chemical suffixes that is why we have decided to share not only this crossword clue but all the Daily Themed Crossword Answers every single day. In case something is wrong or missing kindly let us know by … Common exceptions exist for naming molecular compounds, where trivial or common names are used instead of systematic names, such as ammonia (NH 3) instead of nitrogen trihydride or water (H 2 O) instead of dihydrogen monooxide. .sumbox { If other functional groups are present, the chain is numbered such that the aldehyde carbon is in the "1" position, unless functional groups of higher precedence are present. Numbering of the various substituents and bonds with their locants. Esters (R-CO-O-R') are named as alkyl derivatives of carboxylic acids. Prefixes can be shortened when the ending vowel of the prefix “conflicts” with a starting vowel in the compound. Alkynes are named using the same system, with the suffix "-yne" indicating a triple bond: ethyne (acetylene), propyne (methylacetylene). denature - There are two common meanings for this in chemistry. To avoid long and tedious names in normal communication, the official IUPAC naming recommendations are not always followed in practice, except when it is necessary to give an unambiguous and absolute definition to a compound. Please find below the Common chemistry suffix answer and solution which is part of Daily Themed Crossword April 17 2019 Answers.Many other players have had difficulties with Common chemistry suffix that is why we have decided to share not only this crossword clue but all the Daily Themed Crossword Answers every single day.

Here is a sample molecule with the parent carbons numbered: For simplicity, here is an image of the same molecule, where the hydrogens in the parent chain are removed and the carbons are shown by their numbers: The final name is (6E,13E)-18-bromo-12-butyl-11-chloro-4,8-diethyl-5-hydroxy-15-methoxytricosa-6,13-dien-19-yne-3,9-dione. When the main functional group is a terminal functional group (a group which can exist only at the end of a chain, like formyl and carboxyl groups), there is no need to number it. It should have the maximum number of multiple bonds. By suffix, it is meant that the parent functional group should have a suffix, unlike halogen substituents. nitrate NO 3-and nitrite NO 2- CH3CO-O-OCCH2CH3 is called Ethanoic Propanoic Anhydride. Chemical suffix is a crossword puzzle clue. If the alkyl group is not attached at the end of the chain, the bond position to the ester group is infixed before "-yl": CH3CH2CH(CH3)OOCCH2CH3 may be called butan-2-yl propanoate or butan-2-yl propionate. eg. It can also be named by replacing the -oic acid of their corresponding carboxylic acids with -onitrile. Thus, CH3OCH3 is methoxymethane, and CH3OCH2CH3 is methoxyethane (not ethoxymethane). In organic chemistry, functional groups are specific substituents or moieties within molecules that may be responsible for the characteristic chemical reactions of those molecules. The suffix or ending of the name of a hydrocarbon depends on the nature of the chemical bonds between the carbon atoms. Learning the language of chemistry takes time. The secondary functional groups are: a hydroxy- at carbon 5, a chloro- at carbon 11, a methoxy- at carbon 15, and a bromo- at carbon 18. Propan-1-ol, butan-1-amine, ethanoic acid, ethanoylchloride, butanamide Here is the answer for: Chemistry suffix crossword clue answers, solutions for the popular game LA Times Crossword. For example, CH3COCl is Ethanoyl Chloride. However, the common or trivial name is often substantially shorter and clearer, and so preferred. An alkyl group is a radical of with a certain number of carbons and is of the general formula C n H 2 n + 1 {\displaystyle {\text{C}}_{n}{\text{H}}_{2n+1}} that has had one of its hydrogens removed, freeing up one of its bonds. A prefix is not necessary for the first element if there is only one, so SF6 is 'sulfur hexafluoride'. CH Cyclic alkanes are simply prefixed with "cyclo-": for example, C4H8 is cyclobutane (not to be confused with butene) and C6H12 is cyclohexane (not to be confused with hexene). How to name esters: Esters may be defined as any of a class of organic compounds produced by reactions between acids and alcohols that involve the elimination of water. naming organic compounds worksheet, animal cell coloring answers and prefix suffix root word list are some … If the suffix starts with a consonant or there are two or more of a functional group meaning di, or tri needs to be used then do not remove the the –e from the stem alkane name e.g. On this page you will find the solution to Chemistry suffix crossword clue crossword clue. Polyatomic ions with one fewer oxygen have the suffix “-ous”; ions with two fewer have the prefix “hypo-” and the suffix “-ous.” Strong bases with “-OH” (hydroxide) groups are named like ionic compounds. The first few are: For example, the simplest alkane is CH4 methane, and the nine-carbon alkane CH3(CH2)7CH3 is named nonane. The suffix also appears in some trivial names with reference to oils (from Latin oleum, oil). The Crossword Solver found 20 answers to the chemical suffix crossword clue. Amides (R-CO-NH2) take the suffix "-amide", or "-carboxamide" if the carbon in the amide group cannot be included in the main chain. Ethers (R-O-R) consist of an oxygen atom between the two attached carbon chains. Carboxylic acids attached to a benzene ring are structural analogs of benzoic acid (Ph-COOH) and are named as one of its derivatives. If the acyl groups are different, then they are named in alphabetical order in the same way, with anhydride replacing acid and IUPAC name consists of three words. If you have any other question or need extra help, please feel free to contact us or use the search box/calendar for any clue. It's formula is like aluminum oxide (Al 2 O 3); it's Fe 2 O 3. The Crossword Solver finds answers to American-style crosswords, British-style crosswords, general knowledge crosswords and cryptic crossword puzzles. Multiple double bonds take the form -diene, -triene, etc., with the size prefix of the chain taking an extra "a": CH2=CHCH=CH2 is buta-1,3-diene. Metric or SI (Le Système International d'Unités) prefix are based on powers of ten.They are modifiers on the root word that tell us the unit of measure. ), e.g. General Formula: R-O-R’ where R and R’ are same or different alkyl group. .hide { C The anesthetic Halothane (CF3CHBrCl) is 2-bromo-2-chloro-1,1,1-trifluoroethane. Bibliography of IUPAC Recommendations on Organic Nomenclature, "Improving the Quality of Published Chemical Names with Nomenclature Software", American Chemical Society, Committee on Nomenclature, Terminology & Symbols, https://en.wikipedia.org/w/index.php?title=IUPAC_nomenclature_of_organic_chemistry&oldid=996209695, Articles needing additional references from April 2019, All articles needing additional references, Articles with unsourced statements from January 2012, Wikipedia articles needing clarification from February 2016, Creative Commons Attribution-ShareAlike License, It should have the maximum number of substituents or branches cited as prefixes, It should have the maximum number of substituents of the suffix functional group. Go back to… There are two ethyl- groups. (CH3)3O+ is trimethyloxonium. The same functional group will undergo the same or similar chemical reaction(s) regardless of the size of the molecule it is a part of. Many (but not all) functional groups have a characteristic suffix used in the IUPAC nomenclature system, that identifies that function. If a prefix form is required, "oxo-" is used (as for ketones), with the position number indicating the end of a chain: CHOCH2COOH is 3-oxopropanoic acid. *Note: These suffixes, in which the carbon atom is counted as part of the preceding chain, are the most commonly used. eg. Hydrocarbon Suffixes . IUPAC name: Add the suffix triol to the name of the alkane containing the same number of carbon atoms as the triol. table { Note: # is used for a number. The finalized name should look like this: The IUPAC nomenclature also provides rules for naming ions. 3-ethyl-2,4-dimethylpentane, not 2,4-dimethyl-3-ethylpentane). When numbering from right to left, the ketone groups are numbered 15 and 21. The suffix –ol is used in organic chemistry principally to form names of organic compounds containing the hydroxyl (–OH) group, mainly alcohols (also phenol). The suffix was extracted from the word alcohol. is called pentanenitrile or butyl cyanide. The name of the carboxylate anion is derived from that of the parent acid by replacing the "–oic acid" ending with "–oate." } Any polyatomic ion with the suffix “-ate” uses the suffix “-ic” as an acid. Grouped with the side chains, this gives 18-bromo-12-butyl-11-chloro-4,8-diethyl-5-hydroxy-15-methoxy. Alcohols (R-OH) take the suffix "-ol" with an infix numerical bonding position: CH3CH2CH2OH is propan-1-ol. There is a big … prefixes are ignored for the purpose of alphabetical ordering of side chains (e.g. They would be called "6,13-diene", but the presence of alkynes switches it to 6,13-dien. •When using a suffix, add in the following way : If the suffix starts with a vowel- remove the –e from the stem alkane name e.g. The IUPAC system of nomenclature assigns a characteristic suffix -al to aldehydes. Identification of the remaining functional groups, if any, and naming them by their ionic prefixes (such as hydroxy for -OH, oxy for =O, oxyalkane for O-R, etc.). Again, the substituent groups are ordered alphabetically. For relatively simple molecules they can be more easily understood than non-systematic names, which must be learnt or looked over. Ammonium was adopted instead of nitronium, which commonly refers to NO2+. This is done by first numbering the chain in both directions (left to right and right to left), and then choosing the numbering which follows these rules, in order of precedence. The side chains are: an ethyl- at carbon 4, an ethyl- at carbon 8, and a butyl- at carbon 12. The -oate changes to -ate. It is called tricosa-. Numbering of the chain. General Formula: R-O-R’ where R and R’ are same or different alkyl group. Naming Ionic Compounds Using -ous and -ic . Salts of carboxylic acids are named following the usual cation-then-anion conventions used for ionic compounds in both IUPAC and common nomenclature systems. (di- after #,#, tri- after #,#,#, etc.). The arrangement (with punctuation) is: 18-bromo-12-butyl-11-chloro-4,8-diethyl-5-hydroxy-15-methoxytricosa-6,13-dien-19-yne-3,9-dione, This page was last edited on 25 December 2020, at 04:37. Start studying Organic Chemistry Prefixes and Suffixes. It is published in the Nomenclature of Organic Chemistry (informally called the Blue Book). In order to correctly convert one metric unit to another, you will need to determine which of two prefixes represents a bigger amount and then determine the exponential "distance" between them. The name of each substitution is prefixed to the hydride cation name. Organic Chemistry Nomenclature pertaining to Hydrocarbons. Information about naming esters is included in some school chemistry courses, such as UK A-Level organic chemistry … If the cationic center of the hydride is not a halogen, chalcogen or pnictogen then the suffix "-ium" is added to the name of the neutral hydride after dropping any final 'e'. For example, CH3-CH(OH)-COOH (lactic acid) is named 2-hydroxypropanoic acid with no "1" stated. The highest-precedence group takes the suffix, with all others taking the prefix form. [clarification needed]. The above cations except for methanium are not, strictly speaking, organic, since they do not contain carbon. As a general rule an "ide" suffix indicates an element. "ates" and "ites" always contain oxygen. Common nomenclature uses the older names for some organic compounds instead of using the prefixes for the carbon skeleton above. }. Alternatively, the suffix "-carboxylic acid" can be used, combined with a multiplying prefix if necessary – mellitic acid is benzenehexacarboxylic acid, for example. For example, 3 padding-right: 2.5em; CH It should have the maximum number of single bonds. So I had to specify which one. As there are two, we write 3,9-dione. The position of the hydroxyl group is indicated by arabic numerals. Click here to go back Read more → The alkyl (R') group is named first. Simply add the name of the attached halide to the end of the acyl group. bio G life biochemistry chemistry of living systems carb, -o, -on L coal, carbon carbohydrate compound made of carbon, hydrogen, and oxygen (CH2O)n chem G chemistry chemical kinetics the kinetics of a chemical reaction co, -l, m, -n L with, together coefficient, colligative number that appears with a formula in a chemical equation padding-left:5px; The position of the hydroxyl group is indicated by arabic numerals. empty-cells: hide; There are two double bonds: one between carbons 6 and 7, and one between carbons 13 and 14. If there is more than one of the same type of substituent/double bond, a prefix is added showing how many there are ( di – 2 tri – 3 tetra – 4 then as for the number of carbons below with 'a' added). Amines (R-NH2) are named for the attached alkane chain with the suffix "-amine" (e.g. As with aldehydes, the carboxyl functional group must take the "1" position on the main chain and so the locant need not be stated. The exceptions are hydroxide OH-and cyanide CN-. 2 Ethers (R-O-R) consist of an oxygen atom between the two attached carbon chains. For example, H 2 C=O is methanal, more commonly called formaldehyde.Since an aldehyde carbonyl group must always lie at the end of a carbon chain, it is always is given the #1 location position in numbering and it is not necessary to include it in the name. Functional class IUPAC nomenclature may also be used in the form of alkyl cyanides. Nitriles (RCN) are named by adding the suffix -nitrile to the longest hydrocarbon chain (including the carbon of the cyano group). [citation needed]. When you have a polyatomic ion with one more oxygen than the “-ate” ion, then your acid will have the prefix “per-” and the suffix “-ic.” For example, the chlorate ion is ClO 3 –. The common name for an aldehyde is derived from the common name of the corresponding carboxylic acid by dropping the word acid and changing the suffix from -ic or -oic to -aldehyde. sulfate SO42- and sulfite SO32-, Chemical Formula Table Two iron atoms with plus 3 charge each balances with three oxygen atoms with negative 2 charge each just like the aluminum and oxygen atoms did. For example. visibility: hidden; For each of the compounds A through H shown below, enter the appropriate IUPAC suffix in the designated answer box. margin: 2em; If many substitutions by the same functional group occur, then the number is indicated by prefixing with "di-", "tri-" as with halogenation. nitrate NO3- and nitrite NO2-, 3. } 5) Ethers. If you think this answer is not correct you can leave a comment and we will do our best to help. So the functional group is an ether which gets the suffix “-oxy” or the ending “ether”. If an aldehyde is attached to a benzene and is the main functional group, the suffix becomes benzaldehyde. If there is ambiguity in the position of the substituent, depending on which end of the alkane chain is counted as "1", then numbering is chosen so that the smaller number is used. sulfide S2-, nitride N3- and phosphide P3-, The exceptions are hydroxide OH- and cyanide CN-, 2. Alkenes are named for their parent alkane chain with the suffix "-ene" and an infixed number indicating the position of the carbon with the lower number for each double bond in the chain: CH2=CHCH2CH3 is but-1-ene. CH If there are multiple carboxyl groups on the same parent chain, multiplying prefixes are used: Malonic acid, CH2(COOH)2, is systematically named propanedioic acid. In common nomenclature, in contrast, the prefixes ortho-, meta-, and para- are used to describe the relative positions of groups attached to an aromatic ring. Propanenitrile, ethane-1,2-diol, propanedioic acid, propane-1,2,3-triol, Pentane-2,4-dione. Enter the answer length or the answer pattern to get better results. Definition for OL (2 of 5) a suffix used in the names of chemical derivatives, representing “alcohol” (glycerol; naphthol; phenol), or sometimes “phenol” or less … Example: 2,2,3-trimethyl- . N Has the lowest-numbered locants for multiple bonds (The locant of a multiple bond is the number of the adjacent carbon with a lower number). Branched alkanes are named as a straight-chain alkane with attached alkyl groups. chlorofluoromethane, not fluorochloromethane. CH3F3N+ is trifluoromethylammonium. 1. The groups are on carbon atoms 3 and 9. When numbering from left to right, the ketone groups are numbered 3 and 9. Choose from 500 different sets of o chem prefixes flashcards on Quizlet. For example, (CH3)2CHCH3, commonly known as isobutane, is treated as a propane chain with a methyl group bonded to the middle (2) carbon, and given the systematic name 2-methylpropane. In chemical nomenclature, the IUPAC nomenclature of organic chemistry is a method of naming organic chemical compounds as recommended[1] by the International Union of Pure and Applied Chemistry (IUPAC). 1. As a helpful memory device, one student pointed out on YouTube that Ester is a female name. Thus CH3OCH(CH3)2 is 2-methoxypropane. In common nomenclature, in contrast, the prefixes ortho-, meta-, and para- are used to describe the relative positions of groups attached to an aromatic ring. For example, CH3CO-O-OCCH3 is called Ethanoic Anhydride. If necessary, the bonding position is infixed: CH3CH2CH2NH2 propan-1-amine, CH3CHNH2CH3 propan-2-amine. Click the answer to find similar crossword clues. IUPAC Recommendations on Organic & Biochemical Nomenclature, Symbols, Terminology, etc. If there are different groups, they are added in alphabetical order, separated by commas or hyphens: . So, HNO 3 will be nitric acid. The chemical suffix or end part of a chemical name needs careful attention.. For secondary amines (of the form R-NH-R), the longest carbon chain attached to the nitrogen atom becomes the primary name of the amine; the other chain is prefixed as an alkyl group with location prefix given as an italic N: CH3NHCH2CH3 is N-methylethanamine. HCONH2 Methanamide,CH3CONH2 Ethanamide. Thank you for becoming a member. 3 is less than 15, therefore the ketones are numbered 3 and 9. background-color:#D8F4D7; The shorter of the two chains becomes the first part of the name with the -ane suffix changed to -oxy, and the longer alkane chain becomes the suffix of the name of the ether. For example, C(CH3)4 (neopentane) is named 2,2-dimethylpropane. Two iron atoms with plus 3 charge each balances with three oxygen atoms with negative 2 charge each just like the aluminum and oxygen atoms did. There is a big difference between the "ide", "ate" and "ite" suffixes.. 1. The longest possible main alkane chain is used; therefore 3-ethyl-4-methylhexane instead of 2,3-diethylpentane, even though these describe equivalent structures. It will be called 19-yne. Thus, CH3CO2K can be named as potassium acetate or as potassium ethanoate. For esters such as ethyl acetate (CH3COOCH2CH3), ethyl formate (HCOOCH2CH3) or dimethyl phthalate that are based on common acids, IUPAC recommends use of these established names, called retained names. The names of the first four alkanes were derived from methanol, ether, propionic acid and butyric acid, respectively. As the highest priority functional group, esters get the suffix -oate. Arrangement in this form: Group of side chains and secondary functional groups with numbers made in step 3 + prefix of parent hydrocarbon chain (eth, meth) + double/triple bonds with numbers (or "ane") + primary functional group suffix with numbers. If the oxygen is not attached to the end of the main alkane chain, then the whole shorter alkyl-plus-ether group is treated as a side-chain and prefixed with its bonding position on the main chain. eg. Common names for ketones can be derived by naming the two alkyl or aryl groups bonded to the carbonyl group as separate words followed by the word ketone. Some traditional names for common carboxylic acids (such as acetic acid) are in such widespread use that they are retained in IUPAC nomenclature,[3] though systematic names like ethanoic acid are also used. Simply click on the clue posted on LA Times Crossword on June 5 2019 and we will present you with the correct answer. The N position indicator for amines and amides comes before "1", e.g. This method is especially useful when both groups attached to the oxygen atom are complex.[2]. The numbering of the molecule is based on the ketone groups. These non-systematic names are often derived from an original source of the compound. Multiple groups are dichloro-, trichloro-, etc., and dissimilar groups are ordered alphabetically as before. The first uses prefixes to indicate the number of atoms of an element that are in the compound. There is also an IUPAC nomenclature of inorganic chemistry. They are prefixed with a number indicating the carbon the group is attached to, counting from the end of the alkane chain. Thus water is dihydrogen monoxide. This clue belongs to LA Times Crossword June 5 2019 Answers. However, double and triple bonds only take suffix form (-en and -yn) and are used with other suffixes. eg. It is IUPAC convention to describe all alkenes using absolute descriptors of Z- (same side) and E- (opposite) with the Cahn–Ingold–Prelog priority rules. If the substance is binary (containing only two elements), the suffix -ide is added to the second element. Learning the language of chemistry takes time. The order of remaining functional groups is only needed for substituted benzene and hence is not mentioned here. There is one triple bond between carbon atoms 19 and 20. Commas are put between numbers (2 5 5 becomes 2,5,5), Hyphens are put between a number and a letter (2 5 5 trimethylheptane becomes 2,5,5-trimethylheptane), Successive words are merged into one word (trimethyl heptane becomes trimethylheptane). For Example, CH3CO-R is called Ethanoyl-R. For example, (CH3)2CHCH2CH3 (isopentane) is named 2-methylbutane, not 3-methylbutane. In the mean time we talk concerning Worksheets Chemistry in Biology, we've collected several related pictures to give you more ideas. "cyclohexyl-") or for benzene, "phenyl-". "ates" always have a higher number of oxygen atoms the corresponding "ites". If both acyl groups are the same, then the name of the carboxylic acid with the word acid replaced with anhydride and IUPAC name consists of two words. Chemical suffix is a crossword puzzle clue that we have spotted over 20 times. IUPAC name: Add the suffix triol to the name of the alkane containing the same number of carbon atoms as the triol. In addition, very long names may be less clear than structural formula. The suffixes -diol, -triol, -tetraol, etc., are used for multiple -OH groups: Ethylene glycol CH2OHCH2OH is ethane-1,2-diol. The suffix is -ane if all of the carbon-carbon bonds are single bonds (formula C n H 2n+2), -ene if at least one carbon-carbon bond is a double bond (formula C n H 2n), and -yne if there is at least one carbon-carbon triple bond (formula C n H 2n-2).
