Amides and Imides

Rule C-821

821.1 - Compounds containing one, two, or three acyl groups attached to nitrogen bear the generic name "amide". When only one acyl group is attached to a nitrogen atom, the generic name "primary amide" may be used; when two acyl groups are so attached, the generic name "secondary amide" may be used; and when three acyl groups are so attached, the generic name "tertiary amide" may be used. Amides derived from carbon acids may be termed "carboxamides", those from sulfonic acids "sulfonamides", etc.; N-substituted primary and secondary amides may also be described as acylamines or, more specifically as monoacylamines and diacylamines, respectively.

Note: As the nomenclature of amides of sulfur acids is described (though less extensively) in Rule C-641.8, the present Subsection is illustrated mostly for carbon acids.
