Refrigerant
1. Chlorofluorocarbons (CFCs): - Examples: R12 (Dichlorodifluoromethane) - Properties: CFCs are highly effective as refrigerants due to their stability, non-flammability, and low toxicity. - Environmental Impact: They were found to be damaging to the ozone layer, leading to increased ultraviolet radiation reaching the Earth's surface. This ozone depletion contributed to environmental issues such as skin cancer and climate change. As a result, their use has been phased out under the Montreal Protocol. 2. Hydrochlorofluorocarbons (HCFCs): ...
