Which of the following is the correct reaction of Hinsberg's reagent with primary, secondary and tertiary amines?
- A Tertiary amine forms N, N-dialkyl Benzene sulphonamide which is insoluble in alkali
- B Primary amine forms N-alkyl Benzene sulphonamide which is soluble in alkali
- C Secondary amine forms N, N-dialkyl Benzene sulphonamide which is soluble in alkali
- D Primary amine forms N, N-dialkyl Benzene sulphonamide which is soluble in alkali
Answer & Solution
Correct Answer
(B) Primary amine forms N-alkyl Benzene sulphonamide which is soluble in alkali
Step-by-step Solution
Detailed explanation
Hinsberg's reagent is benzenesulphonyl chloride (\(C_6H_5SO_2Cl\)). Primary amines react with Hinsberg's reagent to form N-alkylbenzenesulphonamide. The hydrogen attached to the nitrogen in the sulphonamide is strongly acidic due to the presence of the strong…
