Explain why benzene requires use of a halogen carrier catalyst to react with bromine while phenol does not.

The oxygen atom in the phenol molecule has a lone pair of electrons. These electrons become delocalised into the aromatic ring, increasing its electron density. This activates the ring. This causes Br
