Answers (1)
N, N-diethyl benzene sulphonamide is not soluble in alkali as it there is no acidic hydrogen present on this. Sulphonyl group is an electron-withdrawing group which is attached to a nitrogen atom.
Hence, (ii) Both assertion and reason are correct statements but reason is not correct explanation of assertion.
