Which test among the following is not used for the distinction among 1 0 , 2 0 and 3 0 aliphatic amine.

Step-by-step solution

Hinsberg test for the detection and distinction of primary, secondary, and tertiary amines in a given sample. Carbylamine reaction is the reaction of a primary amine, chloroform and a base to synthesize isocyanides. Azo dye test is not used for the detection of primary, secondary and tertiary aliphatic amines. The Reaction of Amines with Nitrous Acid, primary and secondary amines react with nitrous acid forming arene diazonium salts and N-nitrosoamine respectively.
