Secondary and tertiary amides bear alkyl group(s) on the nitrogen and just like other substituents, these are placed at the beginning of the name. Notice that the amide carbon, in this case, is not counted as part of the parent chain. When the amide group is connected to a ring, the suffix “carboxylic acid” is replaced with “ carboxamide”: Now, for primary amides, all you need to do is replace the -ic acid, or -oic acid ending with the suffix “ amide”.Īll the substituents are numbered by starting from the amide carbon (unless a higher priority group is present) and placed alphabetically just like for naming any other functional group:
Before going over the principles of naming amides, recall that there are primary, secondary, and tertiary amides.Īmides are derivatives of carboxylic acids and if you have already read about the nomenclature of carboxylic acids, you are familiar with suffixes -ic acid, -oic acid.
