Question

give a chemical test to distingush between a primary and secondary amine

Answer 1

We can apply Hinsberg's test to distinguish between primary, secondary and tertiary amines.

Primary amine reacts with benzenesulphonyl chloride forming N-alkyl benzenesulphonamide, which is soluble in alkali.



Secondary amine reacts with benzenesulphonyl chloride forming N, N-dialkyl benzenesulphonamide, which is insoluble in alkali.
