What aspect of CFCs is responsible for their widespread use?

The widespread use of chlorofluorocarbons (CFCs) can largely be attributed to their chemical stability. CFCs are composed of carbon, chlorine, and fluorine, which gives them a structure that is resistant to breakdown under normal environmental conditions. This stability makes them ideal for various applications, including refrigeration, air conditioning, and aerosol propellants, because they do not easily react with other substances.

Their ability to remain intact in the atmosphere meant that they could effectively transfer heat without degrading too quickly, which contributed to their initial popularity in consumer products. However, this chemical stability is a double-edged sword, as it also leads to their accumulation in the atmosphere and subsequent harmful effects, such as ozone layer depletion.

In contrast, aspects such as cost effectiveness, environmental impact, and efficiency in use, while relevant to the context, do not primarily account for their widespread adoption. CFCs were initially favored for their effectiveness and chemical properties before the environmental impacts became fully understood.
