Question

Which of the following sets of oxides are correctly matched?

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

Hint:

Remember, acidic oxides are formed by non-metals, while basic oxides are formed by metals. Amphoteric oxides exhibit both acidic and basic properties.

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.
