Vedclass · Answer

(C) $PAN$ (Peroxyacetyl nitrate) is a secondary pollutant because it is not emitted directly into the atmosphere but is formed through chemical reactions between primary pollutants.$PAN$ is formed by the photochemical reaction of nitrogen oxides $(NO_x)$ and hydrocarbons in the presence of sunlight (photochemical smog).Since the Reason states that $PAN$ is formed in the absence of light,the Reason is incorrect.Therefore,the Assertion is correct,but the Reason is incorrect.

$A$ : $PAN$ is a secondary pollutant.
$R$ : $PAN$ is formed by interaction of nitrogen oxides and hydrocarbons in the absence of light.
