Bromine itself is not electrophilic enough to react with benzene. But the addition of a strong Lewis acid (electron pair acceptor), such as FeBr 3

Experiment #3 - Hydrocarbons
employees.oneonta.eduAll of the other substances in these reactions are colorless. So, when bromine is added to an alkene or alkyne the red-brown color dissipates quickly, often almost instantly. Bromine can react with an alkane, but this reaction requires heat or ultraviolet light to be successful, and the reaction is a substitution, not an addition: a hydrogen is
