Bromine in carbon tetrachloride (Br2/CCl4) is used for the bromination test, which is a simple chemical test that distinguishes between aromatic compounds and alkenes. Aromatic compounds such as toluene will undergo electrophilic substitution reactions with bromine, whereas alkenes such as vinylbenzene will undergo addition reactions. Therefore, if Br2/CCl4 is added to a mixture of toluene and vinylbenzene, only toluene will react and form a brominated product, indicating the presence of an aromatic ring. Vinylbenzene will remain unchanged.
