Why haloarenes are not reactive towards nucleophilic substitution reaction? Give two reasons.
1. Halorenes are less reactive towards bonds between CX (carbon & halogen) is shorter because benzene is sp2 hybridized having double bond between two carbons.
2. Haloarenes shows resonating structure in which lone pair present on halogen rotates around the benzene ring and charges are delocalised which make it a stable structure and do not easily substitute the halogen group.
