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.
