Bacause of the resonance stabilization of Arylhalides they are unreactive toward normal nuclephilic substitution reactions . However arylhalides having strong electron withdrawing groups at ortho and para positions give aromatic nucleophilic substitution reactions `(S_(N)Ar` mechanism ) , which involves a resonance stablilized carbanion called Meisenheimer complex Which arylhalide is most reactive toward `S_(N)Ar` mechanism ?A. B. C. D. |
