Vedclass · Answer

(C) The reactivity of aryl halides towards nucleophilic aromatic substitution $(ArS_N2)$ increases with the presence of electron-withdrawing groups (like $-NO_2$) at the ortho and para positions.These groups stabilize the intermediate carbanion (Meisenheimer complex) through $-M$ (mesomeric) and $-I$ (inductive) effects.Among the given options,$1$-chloro-$2,4$-dinitrobenzene has two $-NO_2$ groups at the ortho and para positions relative to the chlorine atom,which provide the maximum stabilization to the intermediate.Therefore,it is the most reactive compound.

Which one of the following compounds is most reactive for $ArS_N2$ reaction?
