Question

Phenols do not give protonation reaction readily

Answer 1

The lone pair on oxygen of O-H in phenol is shared with benzene ring through resonance.
Resonance will stabilise it.
So the lone pair is not fully present on oxygen.Hence phenols do not undergo protonation reactions.

Answer 2

Hellooo!!

Electron density on oxygen in phenoxide ion is decreased due to resonance.
The oxygen rather acquire a positive charge.
Therefore phenol does not give protonation readily...

Hope it helps!!
