Question: Which of the following refrigerants has the highest ozone depletion potential (ODP)?
Answer options: ✅ R-12 (dichlorodifluoromethane)
- R-134a (1,1,1,2-tetrafluoroethane)
- R-410A (a blend of R-32 and R-125)
- R-717 (ammonia)
Correct answer: R-12 (dichlorodifluoromethane)
Explanation: R-12, a chlorofluorocarbon (CFC), contains chlorine atoms that are highly destructive to the ozone layer, giving it a high ODP. R-134a and R-410A are HFCs and have an ODP of zero, while R-717 is a natural refrigerant with an ODP of zero.
