Which refrigerant is an HFO?

Hydrofluoroolefins (HFOs) are refrigerants designed to have very low global warming potential compared with traditional HFCs. Among the listed refrigerants, one is an HFO: R-1234yf. It was developed as a low-GWP replacement for R-134a in many applications, including automotive air conditioning, because its environmental impact is far smaller (GWP around 4) than the others. R-134a is a high-GWP HFC, R-22 is an older HCFC with ozone-depleting potential, and R-32 is another HFC with a higher GWP than the HFO. So the HFO in the group is R-1234yf.
