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.
