The cause of the stratosphere's ozone layer depletion is primarily:
Correct answer: A. CF2Cl2
- A. CF2Cl2
- B. C6F6
- C. C6H6F6
- D. C6Cl6
Explanation
Dichlorodifluoromethane (CF2Cl2), also known as Freon-12, is a type of chlorofluorocarbon (CFC). CFCs are the main cause of ozone depletion because they release chlorine atoms in the stratosphere, which catalytically destroy ozone.

About Environmental Chemistry
Atmospheric pollution includes smog, acid rain, greenhouse gases, ozone depletion and the effects of carbon monoxide, sulfur oxides, nitrogen oxides and particulate matter. Water pollution covers sewage, industrial waste, eutrophication and treatment stages, while green chemistry focuses on reducing hazardous substances, waste and energy use through safer, more efficient processes.
