Haloarenes are less reactive than

Question:

 Haloarenes are less reactive than haloalkanes and haloalkenes. Explain.

Solution:

This is because of the resonance stabilization of the aryl ring. If we take an example of C6H5-Cl, there will be a conjugation of chlorine electrons with the electrons in the

ring. This resonance makes C-Cl bond to get partial double bond character and makes less reactive to nucleophilic substitution.
