What is the mechanism involved in the bromination of phenol?

In the bromination of phenol, the mechanism involves the substitution of a hydrogen atom on the phenol ring with a bromine atom. This reaction is typically carried out in the presence of a brominating agent, such as bromine or a bromine-containing compound, under acidic conditions. The bromine atom replaces the hydrogen atom on the phenol ring, resulting in the formation of bromophenol.
