JEE Main2019Chemistry

The reaction that is NOT involved in the ozone layer depletion mechanism in the stratosphere is:

Solution

$C l O ∙ (g) + O (g) C ∙ l (g) + O_{2} (g)$

$C F_{2} C l_{2} (g) uv C ∙ l (g) + C ∙ F_{2} C l (g)$

$H O C l (g) h v O ∙ H (g) + C ∙ l (g)$

All the above three reaction are involved in the ozone layer deplection mechanism.

$C H_{4} + 2 O_{3} 3 C H_{2} = O + 3 H_{2} O$ [not involved]
