Question

what happen when anisole react with hi​

Answer 1

Answer:

Anisole on reaction with HI gains H+ and forms methyl phenyl oxonium ion. Because of resonance, there's some partial double bond character between oxygen and carbon of benzene ring. ... Hence, anisole reacts with HI to give phenol and methyl iodide.

Answer 2

Anisole on reaction with HI gains H+ and forms methyl phenyl oxonium ion.
Because of resonance, there's some partial double bond character between oxygen and carbon of benzene ring.
Thus, it's much easier for I- to attack
