Aryl halides are less reactive towards nucleophilic substitution reaction as compared to alyl halides due to

Options

A. the formation of less stable carbonium ion
B. resonance stabilisation
C. longer carbon-halogen bond
D. `sp^(2)`-hybridised C attach to X

Answer

B

All the aryl (aromatic) compounds are less reactive towards nucleophilic substitution because of the presence of `pi`-electrons (resonance) due to which they repel the incoming nucleophile.
