The hydrogen attached to nitrogen in sulphonamide is strongly
acidic due to the presence of strong electron withdrawing sulphonyl
group Hence, it is soluble in alkali (b) In the reaction with secondary amine, N,N-diethyl-
benzenesulphonamide is formed Rationalised 2023-24

Chemistry
Since N, N-diethylbenzene sulphonamide does not contain any
hydrogen atom attached to nitrogen atom, it is not acidic and hence
insoluble in alkali
