Substitution reaction Steric hindrance caused by the benzene ring of the aryl halide prevents S N2 reactions. Likewise, phenyl cations are unstable, thus making S N1 reactions impossible. In addition, the carbon‐halogen bond is shorter and therefore stronger in aryl halides than in alkyl halides

Answer 2

Answer:

Aryl halides are relatively unreactive toward nucleophilic substitution reactions. This lack of reactivity is due to several factors. Steric hindrance caused by the benzene ring of the aryl halide prevents S N2 reactions

Explanation:

Nucleophilic substitution reactions can occur with aryl halides, provided that strong electron‐withdrawing groups (deactivators) are located ortho and/or para to the carbon atom that's attached to the halogen.
