Assertion : N, N-Diethylbenzene sulphonamide is insoluble in alkali.

Reason : Sulphonyl group attached to nitrogen atom is strong electron withdrawing group.

Note : In the following questions a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices.

Hinsberg reagent/benzenesulphonyl chloride on reaction with secondary amine N,N-diethylbenzenesulphonamide. This compound is insoluble in alkali as it does not contain any reactive acidic hydrogen attached to the nitrogen atom.

The sulphonyl group attached to nitrogen atom is a strong electron withdrawing group but that is not the reason for insolubility of the sulphonamide, the absence of acidic hydrogen.
