Question:
Which compound is mainly responsible for the depletion of ozone layer?
Which compound is mainly responsible for the depletion of ozone layer?
Show Hint
CFCs such as \(CF_2Cl_2\) release chlorine radicals in the stratosphere, which destroy ozone molecules.
Updated On: May 7, 2026
- \(CO_2\)
- \(CH_4\)
- \(CH_3OH\)
- \(CF_2Cl_2\)
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The ozone layer is present in the stratosphere and protects the earth from harmful ultraviolet radiation.
The main compounds responsible for ozone layer depletion are chlorofluorocarbons, commonly called CFCs.
The compound:
\[
CF_2Cl_2
\]
is a chlorofluorocarbon.
In the stratosphere, ultraviolet radiation breaks CFC molecules and releases chlorine free radicals.
These chlorine radicals react with ozone:
\[
O_3
\]
and convert it into oxygen:
\[
O_2.
\]
One chlorine radical can destroy many ozone molecules.
Therefore, the compound mainly responsible for ozone layer depletion among the given options is:
\[
CF_2Cl_2.
\]
