$2,4$-Dinitrochlorobenzene

Vedclass · Answer

(D) The rate of nucleophilic aromatic substitution is directly proportional to the presence of electron-withdrawing groups $(EWG)$ on the aromatic ring. These groups stabilize the negatively charged intermediate (Meisenheimer complex) formed during the reaction. The nitro group $(-NO_2)$ is a strong electron-withdrawing group. Compound $(D)$ contains two $-NO_2$ groups at the ortho and para positions relative to the leaving group $X$,which provides the maximum stabilization to the intermediate,making it the most reactive towards nucleophilic substitution.

In which of the following compounds can the $X^{-}$ atom be most easily substituted by a stronger nucleophile?
