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.

Reactions of Bromine with Selected Compounds. Bromine is a strong electrophile and has a characteristic red-brown color. These properties make bromine a useful reagent for probing the reactivity of colorless nucleophilic organic compounds, such as alkenes and arenes. Two kinds of reaction are common: addition & substitution. In an addition reaction to an alkene two covalent C-Br bonds are formed, and the color of the bromine fades as the colorless product is generated. In a substitution reaction of a hydrocarbon a C-Br covalent bond is also formed, but this product is accompanied by release of of an equal molar quantity of hydrogen bromide gas.
