amide An organic compound containing the group –CO.NH2 (the amide group). Compounds containing this group are primary amides, examples of which are ethanamide (CH3CONH2) and propanamide (C2H5CONH2). They are made by heating the ammonium salt of the corresponding carboxylic acid. Amides can also be made by reaction of ammonia (or an amine with an acyl halid)e. In secondary and tertiary amides, one or both, respectively, of the hydrogens that are attached to the nitrogen atom in a primary amide are replaced by other organic groups.
