Explain the relationship between CFC's and ozone in the stratosphere.

Answer»

UV rays act on CFC's, release Cl atom, which act on ozone to release O2 resulting in ozone layer depletion/causing ozone hole.

Detailed Answer :

The ozone layer is getting depleted by the action of CFCs (Chlorofluorocarbons) used as coolant in refrigerators. UV rays act on CFCs releasing Cl atoms. In presence of Cl (catalyst), ozone degrades releasing molecular oxygen (O2). This causes ozone depletion.
