CFC'S or Chlorofluorocarbons are molecules which demolish the ozone layer. The ozone layer is made up of O3 or ozone molecules these reflect UV rays (harmful ultra violet ligh â¦ t) the CFC'S smash up the O3 into O2 molecules (the type we breathe) these do not reflect UV so we suffer.hlorofluorocarbons (CFCs) are commonly used as the gases used to exchange heat in refrigeration, due to their high volatility. However, when released into the upper atmosphere, their carbon-chlorine bonds are easily broken by solar radiation to release chlorine radicals (unstable chlorine atoms).
