Question

Which of the following compound is used as a refrigerant?

• A. $CC{l}_4$
• B. $CC{l}_2{F}_2$
• C. $C{F}_4$
• D. Acetone

Answer 1

The correct option is B $CC{l}_2{F}_2$

CFCs (Chloro fluorocarbon) non-flammable, tasteless and odourless, and chemically stable. Their other important property is their volatility, having boiling points close to zero degrees Centigrade. These physical properties make them ideal for use as refrigerant gases in air conditioners, freezers and refrigerators.
