Vedclass · Answer

(C) In aryl halides,the halogen atom is attached to an $sp^2$ hybridized carbon atom,making the $C-X$ bond shorter and stronger than in alkyl halides.Nucleophilic substitution in aryl halides is facilitated by the presence of strong electron-withdrawing groups (like $-NO_2$) at the $ortho$ and $para$ positions due to the stabilization of the carbanion intermediate.In $o$-nitrochlorobenzene,$p$-nitrochlorobenzene,and $2, 4, 6$-trinitrochlorobenzene,the $-NO_2$ groups are at positions that allow for resonance stabilization of the intermediate.However,in $m$-nitrochlorobenzene,the $-NO_2$ group at the $meta$ position does not provide resonance stabilization to the carbanion intermediate formed during nucleophilic attack.Therefore,$m$-nitrochlorobenzene has the most difficulty in breaking the $C-X$ bond compared to the other options.

Which of the following compounds has difficulty in breaking the $C-X$ bond?
