Detailed explanation-1: -So, CH4 does not contain a halogen therefore it is not responsible for the depletion of ozone layer.
Detailed explanation-2: -Therefore the chemical which does not deplete the ozone layer among the given options is methane.
Detailed explanation-3: -The CFCs and N2O are very stable in the troposphere, where they are emitted, and are transported to the stratosphere where they release active chemicals that destroy stratospheric ozone through chlorine-or nitrogen oxide–catalyzed processes. They both have substantial anthropogenic sources.
Detailed explanation-4: -chlorofluorocarbons (CFCs) halon. carbon tetrachloride (CCl4) methyl chloroform (CH3CCl3) hydrobromofluorocarbons (HBFCs) hydrochlorofluorocarbons (HCFCs) methyl bromide (CH3Br) bromochloromethane (CH2BrCl) 03-Oct-2021
