Question

Match List-I with List-II. [table] List-I | List-II ; (A) $2SO_2(g) + O_2(g) ightarrow 2SO_3(g)$ | (i) Acid rain ; (B) $HOCl(g) \xrightarrow{h
u} \dot{O}H + \dot{C}l$ | (ii) Smog ; (C) $CaCO_3 + H_2SO_4 ightarrow CaSO_4 + H_2O + CO_2$ | (iii) Ozone depletion ; (D) $NO_2(g) \xrightarrow{h
u} NO(g) + O(g)$ | (iv) Tropospheric pollution [/table] Choose the correct answer from the options given below.

Dr. Abubacker · Accepted Answer

[Solution] Oxidation of $SO_2$ is tropospheric pollution; photolysis of HOCl gives Cl radicals that deplete ozone; acid rain attacks marble ($CaCO_3$); photolysis of $NO_2$ starts photochemical smog. Answer (2).
