Aryl halides are much less reactive than alkyl halides toward nucleophilic substitution mainly because
Achlorine is a much better leaving group in alkyl halides than in aryl halides because of its size
Bthe C-Cl bond has partial double bond character due to resonance with the ring
Cthe C-Cl bond in aryl halides is purely ionic
Dthe benzene ring is too bulky for any nucleophile to approach
Answer: B
A lone pair on chlorine delocalises into the ring, giving the C-Cl bond partial double bond character (and the carbon is sp2). The bond is shorter and stronger and is hard to break. The other statements are not the main reason.
