The mechanism for formation of an amide is as follows taking example of propanoic acid and ethylamine:
The hydrolysis of amide so formed can give back the carboxylic acid and amine.
(b)
Interpretation:
The carboxylic acid and amine or ammonia needs to be identified from which each amide be synthesized.
Concept Introduction:
Amides are formed by a reaction with a carboxylic acid and an amine which are the functional groups. This results in the formation of amide bond, in which OH group of carboxylic acid reacts with one of the H in amine group and CO-NH bond is formed. This bond is known as an amide bond.
