What does chlorofluorcarbons and hydrochlorfluorocarbons have in common?

Chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) are both man-made compounds used primarily as refrigerants, propellants, and solvents. They contain carbon, chlorine, fluorine, and hydrogen atoms in their molecular structures. Both types of compounds have been associated with ozone depletion, although HCFCs are considered less harmful and are being phased out in favor of more environmentally friendly alternatives.
