dichlorodifluoromethane, CCl2F2: consists of a centrally placed carbon atom (shown in black) with two chlorine atoms (shown in green) and two fluorine atoms (shown in purple) arranged approximately (the bond lengths are different) at the points of a tetrahedron around it. dichlorodifluoromethane is a greenhouse gas and ozone depleter.
CFCs or ChloroFluoroCarbons: are very important greenhouse gases and ozone depleters. They contain only carbon, chlorine and fluorine atoms.
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).
