How can you distinguish between CH3CH2 NH2 and
(CH3CH2)2NH by Hinsberg test?
SolutionBenzene sulphonyl chloride (C6H5SO2Cl) (known as Hinsberg's reagent) reacts with 1 and 2 amines to form sulphonamides.With primary (1) amine it forms a product which is soluble in alkali
With secondary (2) amine it forms a product which is not soluble in alkali
No reaction with tertiary (3) amines
This reaction is used for the distinction of 1, 2 and 3 amines.
