Which statement best describes chlorine content in CFCs and HCFCs?

Explanation:
Chlorine is a defining component of both types of compounds. CFCs are fully halogenated carbon compounds that include chlorine (as well as fluorine). HCFCs also contain chlorine, even though they replace some chlorine with hydrogen to make them less persistent. Because chlorine atoms released from these molecules drive ozone destruction in the stratosphere, both CFCs and HCFCs contain chlorine and are of concern. That’s why the statement that both contain chlorine is the best description.
