Nucleophilic Aromatic Substitution Reactions in Haloarenes…

Nucleophilic Aromatic Substitution Reactions in Haloarenes:
(i) Substitution by Hydroxyl Group
(ii) Substitution by Cyano Group
(iii) Phenyl cation formed as a result of self ionisation will not be stabilized by resonance.
(iv) In aryl halide, C-atom holding halogen atom is sp2 hybridized.
(v) The C-X bond in aryl halides have double bond character due to conjugation between lone pair of halogen and benzene ring.
