Methane forms explosive mixtures with air the LEL and UEL values are 5.5% and 14% by volume of air, respectively. The explosion is loudest at 10% volume concentration. The combustion of methane in air forming CO2 involves chain reactions, propagated by free radicals, CH3-, HO-, H-, and O- (Meyer 1989). Being a saturated molecule, the reactivity of methane toward most substances is very low. However, under catalytic conditions, violent reactions have been reported with halogens and certain fluorides of nonmetals. This includes reactions with chlorine at room temperature over yellow mercuric oxide, bromine pentafluoride, oxygen difluoride in the presence of a spark (MeUor 1946, Suppl. 1956), and nitrogen trifluoride (Lawless and Smith 1968).
