R-1234yf is what type?

• A. HFC
• B. CFC
• C. HFO
• D. Natural

Answer: (C)

R-1234yf is an HFO, a hydrofluoroolefin refrigerant. It’s designed as a low-GWP replacement for higher-GWP HFCs, and it has zero ozone depletion potential. What sets it apart is the presence of a carbon–carbon double bond (an unsaturated structure), which classifies it as an olefin rather than a fully saturated HFC. It isn’t a natural refrigerant, since natural options are typically CO2, ammonia, or hydrocarbons and are not synthetic blends like 1234yf.
