R-1234yf is the same as which refrigerant?

• A. R-1234yf
• B. HFO-1234yf
• C. HFC-134a
• D. R-134a

Answer: (B)

R-1234yf and HFO-1234yf are two naming ways for the same refrigerant. The R- prefix is the traditional refrigerant designation, while HFO- indicates the chemical family (hydrofluoroolefin). Both names refer to the same molecule, so they describe the same substance, just using different naming conventions. This matters in labels, service manuals, and specs, where you might see either name and need to recognize they’re the same refrigerant. The other options refer to different compounds (R-134a/HFC-134a are a different refrigerant with higher global warming potential), so they aren’t the same as R-1234yf.
