All Chapters Video 3.6 Naming Carboxylic Acids and Derivatives Chapter OutlineChapter Quiz Question? Ask Dr. Mike! Lesson Summary When naming carboxylic acids, we follow the rules for naming alkenes, except: 1. We number the parent chain in the direction that gives the highest priority (lowest number) to the carboxylic acid group. 2. We replace “ane” with “oic acid”. When naming acid halides: 1. Follow the same rules as for carboxylic acids, and change the suffix to “oyl halide”. When naming esters: 1. The alkyl group attached to the ester oxygen gets listed first with the suffix “yl”. The parent chain then follows. 2. The parent chain starts at the carbonyl carbon and is counted moving away from the ester oxygen. Parent chain’s suffix is replaced with “oate”. When naming amides, we follow the same pattern of naming for esters, except: 1. Any alkyl groups attached to the nitrogen gets listed as “N-methyl”, “N-ethyl”, “N-propyl” etc. 2. The parent chain starts at the carbonyl carbon and is counted moving away from the amide nitrogen. When naming acid anhydrides: 1. Determine the length of the chain on either side of the bridging oxygen. 2. List both lengths alphabetically, replacing each suffix “e” with “oic”. 3. Write “anhydride” at the end of the name. When naming nitriles, follow the same rules for naming alkanes, except: 1. The parent chain is the longest carbon chain that involves the nitrile carbon. 2. Number the parent chain in the direction that gives the smallest number to the nitrile carbon. 3. Add the suffix “nitrile” to the parent name.
