Question

Which of the following statements is correct regarding 'Freons'?

• A. Mixed chlorofluorocarbons such as $CFC{l}_3,C{F}_{2}C{l}_2\text{and}C{F}_{3}Cl$ are known as freons
• B. They are unreactive
• C. They are widely used as refrigeration fluids
• D. All of the above

Answer 1

The correct option is D All of the above

Mixed chlorofluorocarbons such as $CFC{l}_3,C{F}_{2}C{l}_2\text{and}C{F}_{3}Cl$ are known as freons. They are unreactive and non toxic and are widely used as refrigeration fluids, as the propellant in aerosols, and for washing computer boards. Freons are much more effective greenhouse gases in the atmosphere than is $C{O}_2$.
