Organiccompounds made up of atoms of carbon, chlorine (Cl2), and
fluorine (F2). An example is CFC-12 (CCl2F2),
used as a refrigerant in refrigerators and air conditioners and as a foam
blowing agent. Gaseous CFCs can deplete the ozone layer when they slowly rise
into the stratosphere, are broken down by strong ultraviolet radiation, release
chlorine atoms, and then react with ozone molecules.
