Benzene and toluene do not react with bromine in the absence of a catalyst. Phenol is more reactive due to the presence of an electron donating hydroxyl group and reacts with bromine by a substitution reaction forming hydrogen bromide gas.enzene and toluene do not react with bromine in the absence of a catalyst.

Addition reactions In the presence of ultraviolet light (but without a catalyst present), hot benzene will also undergo an addition reaction with chlorine or bromine. The ring delocalisation is permanently broken and a chlorine or bromine atom adds on to each carbon atom.ubstitution into the methyl group If chlorine or bromine react with boiling methylbenzene in the absence of a catalyst but in the presence of UV light, substitution happens in the methyl group rather than the ring. For example, with chlorine (bromine would be similar): The organic product is (chloromethyl)benzene.
