Ozone depletion in the stratosphere is mainly caused by: — Qualitative and Quantitative Analysis Chemistry Question

💡 Solution & Explanation

Step 1: Chlorofluorocarbons (CFCs) are stable in the lower atmosphere but undergo photolysis in the stratosphere to release free chlorine radicals. Step 2: These chlorine radicals act as catalysts that continuously break down ozone molecules into diatomic oxygen. Step 3: Therefore, chlorofluorocarbons are the primary cause of stratospheric ozone depletion, corresponding to option (d).
