Vedclass · Answer

(A) Nucleophilic aromatic substitution reactions are facilitated by the presence of electron-withdrawing groups on the benzene ring. These groups stabilize the intermediate carbanion (Meisenheimer complex) formed during the reaction. The $-NO_2$ group is a strong electron-withdrawing group due to its $-I$ and $-M$ effects. In contrast,$-CH_3$ and $-OCH_3$ groups are electron-donating groups,which destabilize the intermediate carbanion and make the reaction more difficult. Therefore,$p$-nitrochlorobenzene undergoes nucleophilic substitution most easily.
