What is a significant feature of HFCs compared to CFCs?

• A. HFCs are non-toxic
• B. HFCs are cheaper
• C. HFCs are less flammable
• D. HFCs do not contribute to ozone depletion

Answer: (D)

HFCs, or hydrofluorocarbons, are recognized for their significantly lower impact on ozone depletion compared to CFCs, or chlorofluorocarbons. The chemical structure of HFCs does not contain chlorine, which is the element responsible for the depletion of the ozone layer. When CFCs are released into the atmosphere, they eventually break down and release chlorine atoms, which can destroy ozone molecules. In contrast, HFCs do not have this capacity, making them a more environmentally friendly alternative in terms of ozone protection. This characteristic of HFCs aligns with the global shift towards substances that minimize environmental impact, especially concerning ozone layer preservation. While HFCs are more commonly used now, it's important to remain aware of their global warming potential, which is a separate concern from their effects on ozone.
