why halogens are less reactive toward nucleiophilic substitution reaction

Answers

Answered by aaavvviii

Answer:

Hint: Aryl halides are less reactive towards nucleophilic substitution reaction as compared to alkyl halides is because of resonance stabilization in aryl halide. Due to resonance, C−Cl bond becomes shorter and stronger and cannot be easily replaced by nucleophiles.

Answered by beliver4578

As C-X bond in aryl halide acquires a partial double bond character due to resonance while the C-X bond in alkyl halide is a pure single bond. Hence, Bond Strength of Haloarenes is more than that of Haloalkanes. So, Haloarenes are less reactive than Haloalkanes towards nucleophilic substitution !!
