Vedclass · Answer

(A) $I$. Photochemical smog is formed by the action of sunlight on nitrogen oxides and hydrocarbons,resulting in a high concentration of oxidizing agents like $O_3$ and $PAN$. This statement is correct.$II$. Classical smog is a mixture of smoke,fog,and $SO_2$ (reducing smog),not $NO_2$. This statement is incorrect.$III$. High concentrations of $SO_2$ lead to the stiffness of flower buds,which eventually fall off from plants. This statement is correct.$IV$. Normal rain water has a pH of approximately $5.6$ due to the dissolution of atmospheric $CO_2$. $A$ pH of $7.5$ is incorrect. This statement is incorrect.Therefore,statements $I$ and $III$ are correct.

Identify the correct statements from the following:
$I$. Photochemical smog has high concentration of oxidising agents
$II$. $NO_2$ is present in classical smog
$III$. Higher concentration of $SO_2$ in air can cause stiffness of flower buds
$IV$. pH of rain water is approximately $7.5$
