Among the following compounds, which one is not responsible for depletion of ozone layer?
Options
- ACH ₄
- BCFCl ₃
- CNO
- DCl ₂
Correct answer
A. CH ₄
Step-by-step solution
In stratosphere the following reactions takes place which are responsible for depletion of ozone layer. aligned & NO + O ₃ NO ₂+ O ₂ & CF ₂ Cl ₂ h v C F ₂ Cl + Cl & CFCl ₃ h v C FCl ₂+ C l & C 1+ O ₃ Cl O + O ₂ & Cl O + O C + O ₂ & aligned Hence, methane ( CH ₄ ) is not responsible for ozone layer depletion.
