What is the primary gas responsible for the depletion of the stratospheric ozone layer?

💡 Solution & Explanation

Chlorofluorocarbons are synthetic compounds that migrate to the stratosphere where ultraviolet radiation breaks them down, releasing reactive chlorine atoms that catalytically destroy ozone molecules. While carbon dioxide and methane act as greenhouse gases driving global warming, chlorofluorocarbons are directly responsible for stratospheric ozone depletion. Environmental chemistry and ozone protocols are regular features in competitive exams.
