Tardigrade Admin · Accepted Answer

Formation of NO , O 3, NO 2 and CH 2 O occur in photochemical smog. Photochemical smog is a type of air pollution due to reaction of solar radiation with airborne pollutant mixtures of nitrogen oxides (NO) and organic compounds (hydrocarbon). Therefore, oxidation and reduction reactions found in photochemical smog. Thus, option (a) (ii), (iii) and (iv) is correct.

Q. Identify the reactions that occur in photochemical smog.
(i) $C H_{2} = O + H_{2} ⟶ C H_{3} O H$
(ii) $N O_{2} (g) ⟶ h v NO (g) + O (g); O (g) + O_{2} (g) ⟶ O_{3} (g)$
(iii) $3 C H_{4} + 2 O_{3} ⟶ 3 C H_{2} = O + 3 H_{2} O$
(iv) $NO (g) + O_{3} (g) ⟶ N O_{2} (g) + O_{2} (g)$
