Name the chemicals responsible for destruction of the ozone layer. State the main chemical from these chemicals, which is responsible for more than 80% ozone depletion. State the man-made applications which make use of that chemical.

Chemicals responsible for ozone depletion are :

1. Chlorofluorocarbons [CFC i.e., CFCl₃]
2. Methyl chloride [CH₃Cl]
3. Methyl bromide [CH₃Br]
4. Carbontetrachloride [CCl₄]
5. Bromofluorocarbons
6. Methane [CH₄]
7. Nitrous oxide [N₂O]

Out of the above chemicals, Chlorofluorocarbons (CFCs) is the main chemical responsible for more than 80% ozone depletion.

Man-made applications making use of Chlorofluorocarbons (CFCs) are:

1. Aerosol sprays
2. Coolants in refrigeration and A.C.'s
3. Drycleaning fluids
4. Cleansing agents for cleaning electronic components
