प्रश्न
Distinguish between ethylamine, diethylamine, and triethylamine by using Hinsberg’s reagent?
उत्तर
i. Ethylamine (primary amine) reacts with benzenesulphonyl chloride to form N-ethylbenzenesulphonyl amide.
The hydrogen attached to nitrogen in N-ethylbenzene sulphonamide is strongly acidic. Hence it is soluble in alkali.
ii. Diethylamine reacts with benzene-sulphonyl chloride to give N, N-diethyl benzene sulphonamide.
N, N-diethylbenzenesulphonamide does not contain any H-atom attached to the nitrogen atom. Hence it is not acidic and does not dissolve in alkali.
iii. Triethylamine does not react with benzenesulphonyl chloride (i.e., Hinsberg’s reagent) as it does not contain any H-atom attached to the nitrogen atom.
