Vedclass · Answer

(D) Nucleophilic aromatic substitution in aryl halides is facilitated by the presence of electron-withdrawing groups (like $-NO_2$) at the ortho and para positions.These groups stabilize the intermediate carbanion (Meisenheimer complex) through resonance.The more electron-withdrawing groups present,the greater the stabilization of the intermediate,and thus the higher the reactivity toward hydrolysis.$1$-Chloro-$2,4,6$-trinitrobenzene has three $-NO_2$ groups (two ortho and one para),providing the maximum stabilization for the intermediate,making it the most reactive toward nucleophilic substitution.

Which of the following is most reactive toward nucleophilic aromatic substitution (hydrolysis)?
