Discuss the nature of C – X bond in the haloarenes.
Resonance effect: C – X bond holds the nature of a partial double bond character and as a result, C – X bond is very difficult to break.
(i) C – X bond in haloarenes is extremely less reactive towards nucleophilic
(ii) In C – X bond, C atom attached to halogen is sp2 hybridised. A carbon that is sp2 hybridised with a greater s-character is more electronegative in nature and it can hold the electron pair of C – X bond more tightly than sp3 hybridised carbon in haloalkanes with less s-character.
