Fluoromethane, also known as methyl fluoride, Freon 41, Halocarbon-41 and HFC-41, is a non-toxic, liquefiable, and flammable gas at standard temperature and pressure. It is made of carbon, hydrogen, and fluorine. The name stems from the fact that it is methane (CH4) with a fluorine atom substituted for one of the hydrogen atoms. It is used in semiconductor manufacturing processes as an etching gas in plasma etch reactors.[2]
The compound is the lowest mass member of the hydrofluorocarbon (HFC) family, compounds which contain only hydrogen, fluorine, and carbon. These compounds are related to the chlorofluorocarbons (CFC), but since they do not contain chlorine, are not destructive to the ozone layer.[3] Fluorocarbons are, however, potent greenhouse gasses, and the Kigali Amendment to the Montreal Protocol is an attempt to phase them out due to their contribution to global warming.[4]
The C−F bond energy is 552 kJ/mol and its length is 0.139 nm. Its molecular geometry is tetrahedral.
