A) hydrocarbons, ozone and \[S{{O}_{X}}\]
B) hydrocarbons, \[S{{O}_{2}}\]and \[C{{O}_{2}}\]
C) smoke, peroxyacetyl nitrate and \[S{{O}_{2}}\]
D) ozone, peroxyacetyl nitrate and \[N{{O}_{X}}\]
Correct Answer: D
Solution :
Photochemical smog consists of ozone, oxides of nitrogens, peroxiacetyl nitrate and various hydrocarbons (i.e., \[N{{O}_{x}}\]) These are extremely complex in nature. Photochemical smog is formed by UV rays reaction on primary pollutant. The oxidant formed in largest concentration is ozone, which is a serious pollutant in the lower atmosphere.
