Vedclass · Answer

(D) The molecule is $o$-acetotoluidide. The $-NHCOCH_3$ group is a strong ortho/para directing group due to its $+M$ effect,while the $-CH_3$ group is a weak ortho/para directing group due to hyperconjugation.In electrophilic aromatic substitution,the directing effect of the $-NHCOCH_3$ group dominates.Position $4$ is para to the $-NHCOCH_3$ group and ortho to the $-CH_3$ group,making it the least sterically hindered and most electronically activated position for substitution.Therefore,sulphonation is most favourable at carbon number $4$.

Sulphonation is most favourable at the carbon number $...$
