Hydrofluoroolefin leads to ozone depletion
Answers
Answer:
Explanation:
Hydrofluoroolefins (HFOs) are unsaturated organic compounds composed of hydrogen, fluorine and carbon. These organofluorine compound are of interest as refrigerants. Unlike traditional hydrofluorocarbons (HFCs) and chlorofluorocarbons (CFCs), which are saturated, HFOs are olefins, otherwise known as alkenes. HFO refrigerants are categorized as having zero ozone depletion potential (ODP) and low global warming potential (GWP) and so offer a more environmentally friendly alternative to CFCs, HCFCs, and HFCs. HFOs are being developed as "fourth generation" refrigerants with 0.1% of the GWP of HFCs. HFOs currently in use include 2,3,3,3-tetrafluoropropene (HFO-1234yf) and 1,3,3,3-tetrafluoropropene (HFO-1234ze). 1-chloro-3,3,3-trifluoropropene (HFO-1233zd) is also under development.
