Q. What are the main chemical compounds that destroy the ozone layer?
The major chemical compounds that destroy the ozone layer are the CFCs, chlorofluorocarbons, or freons, substances used in the past in refrigerators, spray cans and airconditioners.
The Chlorofluorocarbons react with ozone in the high atmosphere releasing molecular oxygen and thus the amount of ozone in the atmosphere is reduced.
One more substance that destroys the ozone layer is methyl bromide, used in agricultural insecticides.
