Solution
Haloarenes are less reactive than alkyl halides towards nucleophilic substitution because of large C-X bond energy in aryl halide.
Explanation:
The C-X bond takes on a partial double bond nature due to resonance. Haloarenes have a stronger and shorter C-X bond than haloalkanes. As a result, breaking the C-X bond in haloarenes is challenging.
