Question

Relative reactivity of alkyl/ allyl/ benzyl/vinyl and Aryl halides​

Answer 1

Explanation:

Presence of double bond in aryl halide. ... 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.
