Nomenclature of Carboxylic Acid Derivatives Acid Halide Substituents
Gentilucci, Carboxylic Acid Derivatives Nomenclature of Carboxylic Acid Derivatives Gentilucci, Carboxylic Acid Derivatives Acid halides 1. Alkane + the suffix -oyl followed by the halogen. 2. Select the longest continuous carbon chain, containing the acyl group. 3. Number the carbon chain, beginning at the end nearest to the acyl group. 4. Number the substituents and write the name, listing substituents alphabetically. Acid halide substituents attached to rings are named using the suffix - carbonyl. 1 Gentilucci, Carboxylic Acid Derivatives Anhydrides 1. Symmetrical: replace the ending "acid" with "anhydride ". 2. Asymmetrical: select the longest continuous carbon chain, containing the carboxylic acid group, and derive the parent name by replacing the -e ending with -oic anhydride . 3. Number the carbon chain, beginning at the end nearest to the acyl group. 4. Number the substituents and write the name, listing substituents alphabetically. Gentilucci, Carboxylic Acid Derivatives Amides are named by replacing the ending -oic acid with -amide . 1. Select the longest continuous carbon chain, containing the acyl group, and derive the parent name by replacing the -e ending with -amide . 2. Number the carbon chain, beginning at the end nearest to the acyl group. 3. Number the substituents and write the name, listing substituents alphabetically. 4. If the nitrogen atom is further substituted, the substituents are preceded by N- to indicate that they are attached to the nitrogen. Acid halide substituents attached to rings are named using the suffix - carboxamide. 2 Gentilucci, Carboxylic Acid Derivatives Carboxylate esters 1. Select the longest continuous carbon chain containing the acyl group, and derive the parent name by replacing the -e ending with –oate .
