  • Carbon tetrafluoride - Wikipedia

    Tetrafluoromethane, also known as carbon tetrafluoride or R-14, is the simplest perfluorocarbon (C F 4).As its IUPAC name indicates, tetrafluoromethane is the perfluorinated counterpart to the hydrocarbon methane.It can also be classified as a haloalkane or halomethane.Tetrafluoromethane is a useful refrigerant but also a potent greenhouse gas. It has a very high bond strength due to the
