Chloroflurocarbons are responsible for the depletion of the ozone layer. Which one of the following reacts with ozone to form oxygen?
Chloroflurocarbons (CFCs) released into the atmosphere reach the stratosphere. When UV radiation strikes CFCs, they breakdown to give chlorine and some other compounds. This chlorine reacts with ozone molecules and converts them to oxygen. This disrupts the ozone cycle and slowly leads to the depletion of the ozone layer.
