R-11 and R-12 are which type of refrigerants?

Explanation:
R-11 and R-12 are chlorofluorocarbons. Their molecules contain chlorine, fluorine, and carbon, with no hydrogen, which is why they’re categorized as CFCs. The chlorine in these compounds is what caused ozone depletion, leading to international phaseouts and replacements with safer options. They aren’t HCFCs because those contain hydrogen; they aren’t HFCs because those lack chlorine (they may have hydrogen and fluorine). They aren’t natural refrigerants, which are typically ammonia, CO2, or hydrocarbons and don’t rely on these halogens.
