Question:
An amine on reaction with benzenesulphonyl chloride produces a compound insoluble in alkaline solution. This amine can be prepared by ammonolysis of ethyl chloride. The correct structure of amine is :
$\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{NH}_{2}$
$\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{NHCH}_{3}$
Correct Option: , 4
Solution:
It has to be $2^{\circ}$ amine because on reaction with benzene sulphonylchloride it gives water in soluble product. As it is formed by ammonolysis of ethylchloride, so it has to be R-NH-Et type.
