Question

Ozone in the stratosphere is deleted by:

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

Answer 1

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

The presence of $CFCs$ in the atmosphere results in the depletion of the ozone layer. The chemical formula of this substance is $C{F}_{2}C{l}_2$​. They are used as coolants in refrigerators, coolers, etc. The $CFCs$ causes the breaking of the ozone molecule which forms the oxygen radical and $O_2$​. The depletion of the ozone layer results in the penetration of harmful UV radiations from the sun into the Earth's atmosphere.

Thus, the correct answer is an option A.
