Vedclass · Answer

(A) The ozone layer is depleted by substances that release reactive radicals like $Cl^{\bullet}$ or $NO^{\bullet}$ in the stratosphere.$CFCl_3$ (a chlorofluorocarbon) releases $Cl^{\bullet}$ radicals.$NO$ (nitric oxide) reacts with ozone to form $NO_2$ and $O_2$.$Cl_2$ can also lead to the formation of chlorine radicals.$CH_4$ (methane) is not responsible for ozone depletion; in fact,it reacts with chlorine radicals $(Cl^{\bullet} + CH_4 \rightarrow CH_3^{\bullet} + HCl)$ and helps in removing them from the stratosphere,thereby acting as a sink for chlorine radicals.

Among the following compounds,which one is not responsible for the depletion of ozone layer?
