Haloarenes are less reactive than haloalkanes and haloalkenes. Explain.

This is a short answer type question as classified in NCERT Exemplar

The resonance stabilisation of the aryl ring is the main reason haloarenes are less reactive than haloalkanes and haloalkenes. The electron pairs on the halogen atom, for example, are conjugated with the ring's -electrons in C₆H₅ - Cl. The C-Cl link takes on a partial double bond character as a result of resonance, making it less reactive to nucleophilic substitution than haloalkanes and haloalkanes.
