$B$

Vedclass · Answer

(B) The molecule contains an acetamido group $(-NHCOCH_3)$ and a methyl group $(-CH_3)$ attached to the benzene ring.Both groups are ortho/para directing.The $-NHCOCH_3$ group is a stronger activating group due to the $+M$ effect of the nitrogen lone pair compared to the $+I$ and hyperconjugation effect of the $-CH_3$ group.Therefore,the substitution is primarily directed by the $-NHCOCH_3$ group.Position $A$ is ortho to the $-NHCOCH_3$ group but is sterically hindered by the adjacent $-CH_3$ group.Position $C$ is ortho to the $-NHCOCH_3$ group and is less sterically hindered.Position $B$ is para to the $-NHCOCH_3$ group.Generally,para-substitution is preferred over ortho-substitution due to lower steric hindrance.Thus,position $B$ is the most favourable site for $EAS$.

Identify the position where electrophilic aromatic substitution $(EAS)$ is most favourable.
