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
A different type of treatment for certain amines is also described below (Rule C-11.4).
Derivatives and Radicals from Carboxylic Acids
Aldehydes and Nitriles
