Step-by-step solution

Gabriel phthalimide synthesis is the best method for preparing pure primary aliphatic amines, as it avoids the formation of secondary and tertiary amines. (A 4) Hoffmann bromamide degradation reaction converts an amide into a primary amine with one carbon less than the parent amide. (B 3) Carbylamine reaction is a test for primary amines that involves the formation of an isocyanide, which is a foul-smelling compound. (C 1) Hinsberg test uses benzenesulphonyl chloride as the reagent to distinguish between primary, s
