Read the following passage and answer the questions that
How can you distinguish between CH3CH2 NH2 and
(CH3CH2)2NH by Hinsberg test?
- Benzenesulphonyl chloride (C6H5SO2Cl) (known as Hinsbergs 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.
