Vedclass · Answer

(C) The correct answer is that the ozone hole is the thinning of the ozone layer in the stratosphere at some places.It is not a literal hole,but a significant reduction in the concentration of ozone $(O_3)$ in the stratosphere.The depletion is primarily caused by compounds like $NO_x$ and $CFCs$ (Chlorofluorocarbons).The chemical reactions involved are:$NO_2 + O_3 \rightarrow NO_3 + O_2$$CF_2Cl_2 \rightarrow CF_2Cl + Cl$$\dot{Cl} + O_3 \rightarrow Cl\dot{O} + O_2$$Cl\dot{O} + O \rightarrow \dot{Cl} + O_2$These reactions occur in the stratosphere.
