Resonance stabilization

Vedclass · Answer

(B) Aryl halides are less reactive towards nucleophilic substitution reactions compared to alkyl halides primarily due to resonance stabilization. In aryl halides,the lone pair of electrons on the halogen atom is in conjugation with the $\pi$-electrons of the benzene ring. This results in the development of partial double bond character in the $C-X$ bond,making it shorter and stronger,which is difficult to break. Additionally,the $sp^2$ hybridized carbon atom attached to the halogen is more electronegative,further strengthening the bond.

Aryl halides are less reactive than alkyl halides towards nucleophilic substitution reactions due to:
