- Hydrochlorofluorocarbons (HCFCs) are a group of man-made compounds containing hydrogen, fluorine and carbon.
- These are ozone depleting substances and potent greenhouse gases that are controlled under the Montreal Protocol.
- HCFCs usually dissolve in water, but do not dissolve in organic (carbon-containing) solvents.
- HCFCs are used in a wide variety of applications, including refrigeration, air conditioning, foam blowing, solvents, aerosols, and fire suppression.

Your Answer Is Correct
Your Answer Is Wrong
Explanation :
- Hydrochlorofluorocarbons (HCFCs) are a large group of compounds, whose structure is very close to that of Chlorofluorocarbons (CFCs), but including one or more hydrogen atoms.
- These contain carbon, hydrogen, chlorine and fluorine.
- Under normal conditions, HCFCs are gases or liquids which evaporate easily. They are generally fairly stable and unreactive.
- HCFCs do not usually dissolve in water, but do dissolve in organic (carbon-containing) solvents. HCFCs are also part of a group of chemicals known as the volatile organic compounds (VOCs).
- Hydrochlorofluorocarbons (HCFCs) are ozone depleting substances and potent greenhouse gases that are controlled under the Montreal Protocol.
- HCFCs are used in a wide variety of applications, including refrigeration, air conditioning, foam blowing, solvents, aerosols and fire suppression.
