What properties of CFCs make them ideal for various commercial applications but also make them a long-term problem in the stratosphere?

Chlorofluorocarbons (CFCs) are stable, non-toxic, and non-flammable compounds that have low boiling points, making them ideal for use as refrigerants, propellants, and solvents. Their chemical stability allows them to remain in the atmosphere for extended periods, which is beneficial for commercial applications but problematic for environmental impact.

CFCs contribute to ozone layer depletion when they are released into the atmosphere. Once in the stratosphere, UV radiation breaks down CFCs, releasing chlorine atoms that catalyze the destruction of ozone molecules, leading to increased UV radiation reaching the Earth's surface, which can cause health and environmental issues.

CFCs have a high Global Warming Potential, meaning they can trap heat in the atmosphere much more effectively than carbon dioxide. This property, combined with their long atmospheric lifetime, makes CFCs significant contributors to climate change, posing a long-term environmental challenge despite their utility in various applications.
