Question

Ozone in stratosphere is depleted by:

• A. $C_6{F}_6$
• B. $C_7{F}_{16}$
• C. $C{F}_{2}C{l}_2$
• D. $C_6{H}_{6}C{l}_6$

Answer 1

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

Dichlorodifluoromethane $\left(C{F}_{2}C{l}_2\right)$ is used as a refrigerant gas in refrigerators and air conditioners. Dichlorodifluoromethane is also used in aerosol sprays, in plastics, and as an aid in detecting leaks. Dichlorodifluoromethane harms the ozone layer, which protects the earth from the sun's ultraviolet radiation.

Hence the correct answer is option C.
