Methane + bromine
It is used as a solvent for greases, waxes, and oils, in plastic and rubber industry for blowing and vulcanization, further for polymerization, as a sedative and as an intermediate in manufacturing agrochemicals. Due to its non-flammability it is used as an ingredient in fire-resistant chemicals. It is also used for separating minerals because of its high density.

WebThe chlorine–chlorine and bromine–bromine bonds are stronger (240 kJ/mol and 190 kJ/mol respectively). They are strong enough to make us need to provide some energy to kick-start the substitution reactions. We commonly do this by shining ultraviolet light (UV light) through the reaction mixture. Here is the chlorination of methane:
