Question

Which radical is responsible for depletion of ozone in stratosphere?

• A. \( \cdot \text{Cl} \)
• B. \( \cdot \text{F} \)
• C. \( \cdot \text{CH}_3 \)
• D. \( \cdot \text{CF}_2\text{Cl} \)

Hint:

Chlorine radicals are the primary contributors to the depletion of ozone in the stratosphere. They act as catalysts in the breakdown of ozone molecules.

Answer 1

The Correct Option is A

Chlorine radical (\( \cdot \text{Cl} \)) is well-known to play a significant role in the depletion of ozone in the stratosphere. The chlorine radicals catalytically break down ozone molecules (\( \text{O}_3 \)) into oxygen molecules (\( \text{O}_2 \)) and oxygen atoms (\( \text{O} \)), leading to a reduction in the ozone layer.
Thus, \( \cdot \text{Cl} \) is the correct radical responsible for ozone depletion.
