what is self ionisation of haloarenes

Answers

Answered by King412

Answer:

In haloarenes, the phenyl cation formed is by self ionisation,and is not stabilised by resonance. Because sp2 hybridised orbital of carbon bearing positive charge is perpendicular to the p-orbitals of the phenyl ring. Hence substitution by formation of cation (intermediate) is not possible.
