HCFC refrigerants are based on which combination of elements?

HCFC refrigerants are based on which combination of elements?

• A. Chlorine based
• B. Hydrogen and chlorine based
• C. Hydrogen based
• D. Fluorine based

Answer: (B)

HCFC stands for hydrochlorofluorocarbons, so their molecules include hydrogen along with chlorine, carbon, and fluorine. The defining aspect that sets them apart from pure chlorine- or fluorine-based compounds is the presence of hydrogen, which differentiates HCFCs from CFCs (no hydrogen) and from strictly fluorine- or chlorine-based groups. Among the options, hydrogen and chlorine based best captures the core composition, even though fluorine and carbon are also part of the molecule.
