fluoromethane or methyl fluoride CH₃F: consists of a centrally placed carbon atom with three hydrogen atoms and one fluorine atom arranged at the points of a tetrahedron around it. It is equivalent to methane molecule with one hydrogen atom replaced by a fluorine atom. It is an HFC.

HFCs or Hydro Fluoro Carbons contain only carbon, hydrogen and fluorine. Hydrofluorocarbons are being adopted in preference to the related hydrocarbons that contain chlorine and fluorine (the CFCs). HFCs are still greenhouse gases but (because they do not generate reactive chlorine) they do not destroy ozone in the ozone layer.

Haloalkanes are formed when a halide atom (Fluorine, Chlorine, Bromine, or Iodine) is bonded to carbon in an alkane. An alkane is a compound made fron carbon and hydrogen (i.e. it is a hydrocarbon) with no multiple bonds (i.e. it is saturated). Examples include methane (CH₄) ethane (C₂H₆), propane (C₃H₈), and butane (C₄H₁₀).
