प्रश्न
Describe Hinsberg method for the identification of primary, secondary and tertiary amines. Also write the chemical equations of the reactions involved.
उत्तर
Hinsberg's method: Benzenesulphonyl chloride (C6H5SO2Cl) (known as Hinsberg’s reagent) reacts with primary and secondary amines to form sulphonamides. The method is used for the distinction of primary, secondary and tertiary amines.
Sulphonamide formed in case of a primary (1°) amine is soluble in an alkali.
Sulphonamide formed in case of a secondary (2°) amine remains insoluble in an alkali.
A tertiary (3°) amine does not give a positive Hinsberg test.
