In stratosphere `CFCs` gets broken down by the action of powerful `UV` radiation releasing:

A

`overset(.)CH_(3)`

B

`overset(.)ClO`

C

`overset(.)Cl`

D

`overset(.)CFCl_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C

`CFCs` gets broken by the action of `1UV` radiation coming from the sun and produced `overset(.)(C )l` radicals
`CF_(2)Cl_(2) overset(UV)(rarr) CF_(2)overset(.)(C )l+overset(.)(C )l`.

Assertion: In the stratosphere, ozone is produced by the action of UV radiations on dioxygen. Reason: UV radiations split the molecules oxygen into free oxygen (O) atoms which combine with molecular oxygen to form ozone.

CFC s split up in strastosphere to release chlorine by the action of

Assertion : Ozone is getting depleted due to CFCs Reason: With depelction of ozone layer more UV radiation filters into troposphere

Ozone is an unstable, dark blue diamagnetic gas. It absorbs strongly the UV radiation, thus proteching the people on the earth from the harmful UV radiation from the sun. The use of chloroflurocarbon (CFC) in aeroslos and refrigrators, and their subsequent escape into the atomsphere, is blamond for making holes in the ozone layer over the Antarctic, and Arctic. Ozone acts as a strong oxdising agent in acidic and alkaline medium. For this property ozone is used as a germicide and disinfectant for sterillising water and improving the atmosphere of croweded places. CFC damages ozone layer by reactions :
