Match List-I with List-II :

List-I         -          List-II

(a) 2SO2(g) + O2(g) → 2SO3(g) → (i) Acid rain

(b) HOCl(g) + hv → \(\dot{OH}\) + \(\dot{Cl}\) → (ii) Smog

(c) CaCO3 + H2SO4 → CaSO4 + H2O + CO2 →(iii) Ozone depletion

(d) NO2(g) + hv → NO(g) + O(g) → (iv) Tropospheric pollution

Choose the correct answer from the options given below.

(1) (a)-(i), (b)-(ii), (c)-(iii), (d)-(iv)

(2) (a)-(ii), (b)-(iii), (c)-(iv), (d)-(i)

Correct answer: (3) (a)-(iv), (b)-(iii), (c)-(i), (d)-(ii)

Explanation:

(a) 2SO2(g) + O2(g) → 2SO3(g) → (iv) Tropospheric pollution 

(b) HOCl(g) + hv → \(\dot{OH}\) + \(\dot{Cl}\) → (iii) Ozone depletion

(c) CaCO3 + H2SO4 → CaSO4 + H2O + CO2 → (i) Acid rain

(d) NO2(g) + hv → NO(g) + O(g) → (ii) Smog
