Which refrigerant is an HCFC example?

Explanation:
HCFCs are refrigerants that contain hydrogen as well as chlorine, making them less ozone-depleting than pure CFCs but still contributing to ozone loss. Among common options, the clear HCFC example is R22. R11 is a CFC with no hydrogen, so it’s not HCFC. R502 is a blend that includes a CFC component, so it isn’t a straightforward HCFC example. R407C is an HFC blend and contains no chlorine, so it isn’t an HCFC either. Therefore, R22 best represents the HCFC class.
