Question

Which of the following halide of carbon is used as refrigerant?

• A. $CH{I}_4$
• B. $C{F}_4$
• C. $C{H}_{2}C{l}_2$
• D. $C{F}_{2}C{l}_2$

Answer 1

The correct option is D $C{F}_{2}C{l}_2$

CFCs are chlorofluorocarbons - compounds containing carbon with chlorine and fluorine atoms attached.

CFCs are non-flammable and not very toxic. They are used as refrigerants, propellants for aerosols, for generating foamed plastics like expanded polystyrene or polyurethane foam, and as solvents for dry cleaning and for general degreasing purposes.

Example: $C{F}_{2}C{l}_2$

Option D is correct.
