Question

Chlorofluorocarbons have been in use in refrigerators and air conditioners are proved to be unfriendly to the environment. Substitutes to these compounds which are friendly to the environment are:

• A. $CC{l}_2$
• B. $C{Cl}_{3}F$
• C. $CCl{F}_{2}CCl{F}_2$
• D. $C{F}_{3}C{H}_{2}F$

Answer 1

The correct option is D $C{F}_{3}C{H}_{2}F$

The first three compounds are chlorofluoro carbons which are harmful to ozone and unfriendly to the environment. These are used in refrigerators. so a compound called $C{F}_{3}C{H}_{2}F$ was discovered, which is friendly to the environment and used in refrigerators.
