Question

“Ozone is a pollutant.” True or false?

(a) True

(b) False

I had been asked this question in an interview for job.

I want to ask this question from P-Block Elements in chapter P-Block Elements of Chemistry – Class 12

Answer 1

Correct choice is (a) True

The explanation: Although ozone protects us from harmful UV rays, at ground level it is a highly toxic and irritating gas. It is referred to as a ‘secondary pollutant’ since it is formed from the combination of two primary pollutants, namely nitrogen oxides (NOX) and volatile organic compounds (VOCs).
