Give reasons for the following : (i) The bond length of the C–Cl bond is larger in haloalkanes than that in haloarenes
The C linked to the halogen atom in haloalkanes is sp3sp3 hybridized, whereas it is sp2sp2 hybridized in haloarenes. In haloarene, the halogen is in resonance with the benzene ring. Due to this, there is a partial double bond character between halogen and carbon which results in a shorter bond length.
