Vedclass · Answer

(C) Nucleophilic aromatic substitution reactions in haloarenes are facilitated by the presence of electron-withdrawing groups (like $-NO_2$) at the ortho and para positions relative to the halogen atom. These groups stabilize the carbanion intermediate formed during the reaction. Among the given options,$2,4-$dinitrochlorobenzene has two $-NO_2$ groups at the ortho and para positions,which provide the maximum stabilization to the intermediate,making it the most reactive towards nucleophilic substitution with sodium methoxide.

The compound that reacts the fastest with sodium methoxide is
