Haloarenes are less reactive than haloalkanes and haloalkenes, Explain.

Due to resonance, C— X bond in haloarenes and haloalkenes have some double bond

character. This partial double bond character of C— X bond ‘strengthen the bond. So,

haloarenes and haloalkenes are less reactive than haloalkanes.

Lets see the resormaliny structure of the haloarenes and haloalkenes

Now, more the number of resonating structure higher will be the stability of the compound

and lesser will be the reactivity. In haloarenes, more resonating structures are observed than

the haloalkenes. So, haloarenes are less reactive than haloarenes. In haloalkanes, this

— X bond is purely single bond.
