A compound that undergoes bromination easily is phenol. Due to presence of −OH(+M) group the ring becomes much more active in substitution reactions. The bromination occurs due to availability of electrons on ortho and para position.
In toluene CH3 group show +HC which is less activating group than -OH & -COOH (-M) ring deactivating group.
more activating group given E+ substitution (bromination) easily.
