Detailed Solution

During the bromination of any non polar substance like benzene, Lewis acid is used to polarize the attacking electrophile Br₂.

But in case of highly polar phenol molecule, the oxygen atom present in the phenol molecule itself polarizes the incoming electrophile Br₂to form ions. SO in this case no additional Lewis acid is required.
