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 that destroy ozone in the stratosphere.
Updated On: May 7, 2026
- \(CO_2\)
- \(CH_4\)
- \(CH_3OH\)
- \(CF_2Cl_2\)

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: The ozone layer protects the earth from harmful ultraviolet radiation.
Step 2: Chlorofluorocarbons, commonly called CFCs, are mainly responsible for ozone layer depletion.
Step 3: \(CF_2Cl_2\) is a chlorofluorocarbon.
Step 4: In the stratosphere, CFCs release chlorine radicals under the action of UV radiation. \[ CF_2Cl_2 \xrightarrow{UV} Cl^\cdot + \text{other products} \]
Step 5: Chlorine radicals destroy ozone molecules repeatedly. \[ Cl^\cdot + O_3 \rightarrow ClO^\cdot + O_2 \]
Step 6: Hence, \(CF_2Cl_2\) is mainly responsible for ozone layer depletion. \[ \boxed{CF_2Cl_2} \]
