On the basis of chemical reactions involved, explain how do chlorofluorocarbons cause thinning of ozone layer in stratosphere ?

Explanation

### Step-by-Step Solution:

1. **Understanding Chlorofluorocarbons (CFCs)**:
- Chlorofluorocarbons, abbreviated as CFCs, are chemical compounds primarily used in aerosol sprays, refrigerants, and other industrial applications. They contain chlorine, fluorine, and carbon.

2. **Release of CFCs into the Atmosphere**:
- When products containing CFCs are used, these compounds are released into the atmosphere. Once in the atmosphere, they can rise to the stratosphere.
