$1-$Chloro$-4-$nitrobenzene

Vedclass · Answer

(B) Nucleophilic aromatic substitution reactions occur more readily when electron-withdrawing groups (EWGs) are present on the benzene ring. These groups stabilize the negatively charged intermediate (Meisenheimer complex) formed during the reaction. The $-NO_2$ group is a strong electron-withdrawing group due to its $-I$ and $-M$ effects,which significantly stabilizes the carbanion intermediate. Therefore,$1$-chloro-$4$-nitrobenzene undergoes nucleophilic substitution most easily.

Which of the following compounds undergoes nucleophilic substitution reaction most easily?
