Ultraviolet radiations from sunlight causes a reaction that produces
Ultraviolet radiations from sunlight causes a reaction that produces
Updated On: Jul 12, 2022
- fluorides
- carbon monoxide
- sulphur dioxide
- ozone.
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Ozone is generated in the lower atmosphere during the formation of photochemical smog when nitrogen dioxide splits to produce reactive oxygen atoms which combine with molecular oxygen. Oxygen molecules split under ultraviolet radiations to produce oxygen atoms which combine with molecular oxygen to form ozone. It is this gas which forms the protective ozone umbrella in the stratosphere and shield life from biocidal high energy ; radiations. It can also damage DNA molecules and cause j carcinogenesis.
