Substitutive Nomenclature

C-0.11. Exceptional Treatment of Some Characteristic Groups

There are two methods of using suffixes in substitutive nomenclature for aliphatic carboxylic acids and their derivatives, for aliphatic nitriles, and for aliphatic aldehydes; of these methods, one involves modification of the preceding rules, the other does not, as illustrated for carboxylic acids by Rules (a), respectively, below. However, when the characteristic group concerned is attached to a ring, only the method of Rule C-11.11 (b) is used in systematic nomenclature.

A different type of treatment for certain amines is also described below (Rule C-11.4).

Carboxylic Acids
Derivatives and Radicals from Carboxylic Acids
Aldehydes and Nitriles
