Bromine reacts with saturated hydrocarbons by displacing hydrogen atoms. This process is a type of substitution reaction, where an atom or group in a molecule is replaced by another.12

While bromine is capable of this reaction, it does not occur as readily as it does with chlorine. These reactions often involve free radicals, which are highly reactive species that can participate in chain processes.132
