Amide can also refer to the conjugate base of ammonia (the anion H2N−) or of an organic amine (an anion R2N−). For discussion of these "anionic amides", see Alkali metal amides.

In chemistry, an amide is one of two kinds of compounds: the organic functional group characterized by a carbonyl group (C=O) linked to a nitrogen atom (N), or a compound that contains this functional group (pictured to the right); or. a particular kind of nitrogen anion.

Definition of amide. Amides (RCONH2) are functional group where carbonyl group attached to a amine group. In simple amides nitrogen attached with two hydrogen atoms.

An amide functional group consists of a carbonyl group bonded to a nitrogen. In simple amides, two hydrogen atoms are bonded to the nitrogen (-CONH2) while in more complex amides, the nitrogen is bonded to one or two aliphatic or aromatic groups (-CONR).
