Vedclass · Answer

(D) The reaction involving the cleavage of the $C-X$ bond in haloarenes is Nucleophilic Aromatic Substitution $(S_NAr)$.This reaction is facilitated by the presence of electron-withdrawing groups (like $-NO_2$) at the ortho and para positions,which stabilize the carbanion intermediate formed during the reaction.Compound $I$ has one $-NO_2$ group at the para position.Compound $II$ has two $-NO_2$ groups (one at ortho and one at para position).Compound $III$ has three $-NO_2$ groups (two at ortho and one at para position).As the number of electron-withdrawing groups increases,the reactivity towards nucleophilic substitution increases.Therefore,the correct order of reactivity is $III > II > I$.

The correct order of reactivity for the reaction involving the cleavage of the $C-X$ bond in the following compounds is:
