Discuss the nature of C—X bond in the haloarenes.

This is a short answer type question as classified in NCERT Exemplar

Resonance effect: Because the C – X bond has the characteristics of a partial double bond, it is extremely difficult to break.

(i) The C - X bond in haloarenes is extremely less reactive to nucleophilic groups 

(ii) The C atom linked to the halogen is sp² hybridised in the C – X bond. Carbon that has been sp² hybridised with a higher s-character is more electronegative in nature and can retain the electron pair of the C - X bond more tightly than carbon that has been sp³ hybridised with a lower s -character in haloalkanes.
