- Tetrahalomethane
Tetrahalomethanes are fully halogenated
methane derivatives of general formula CBrkCllFmIn.Tetrahalomethanes are on the border of inorganic and organic chemistry, thus they can be assigned both inorganic and organic names by
IUPAC : tetrafluoromethane - carbon tetrafluoride, tetraiodomethane - carbon tetraiodide, difluorodichloromethane - carbon dichloride difluoride.Each
halogen (F, Cl, Br, I) forms corresponding halomethane, but their stability decreases in order CF4 > CH4 > CCl4 > CBr4 > CI4 from exceptionally stable gaseous tetrafluoromethane with bond energy 515 kJ.mol-1 to solid tetraiodomethane. It depends onbond energy .Also many mixed halomethanes are well known.
Uses
Fluorine and chlorine, sometimes bromine-substituted halomethanes are used as
refrigerant s.See also
