Why haloarenes are less reactive than haloalkanes?
Haloarenes is less reactive than haloalkanes due to haloarenes electron pair on halogen atom is in conjugation with pi electron of ring. Since the bond cleavage in the haloarenes is difficult than haloalkanes. Since resonance carbon-halogen in aryl halide because it possesses double bond character. Thus, haloalkanes are more reactive than haloarenes.
