MCQ
The major pollutants to deplete ozone are :
- ✓Chlorofluorocarbons
- BNitrogen oxides
- CHydrocarbons
- DAll of the above
✓
Answer
Correct option: A.
Chlorofluorocarbons
Pollution leads to the addition of harmful components in the environment which adversely affect the quality of the environment. $\text{CFCs}$ is an organic compound and a volatile derivative of methane, ethane, and propane. It is known as Freon. They are used as a refrigerant. The radical chlorine escapes from $\text{CFC}$ in the presence of $\text{UV}$ radiation and is long lived in the upper atmosphere where it catalyzes the conversion of ozone into oxygen molecule.
