Vedclass · Answer

(C) The correct matching is as follows:$(a)$ $2 SO_{2(g)} + O_{2(g)} ightarrow 2 SO_{3(g)}$ represents the formation of $SO_3$ which leads to acid rain,so $(a)-(iv)$ (as it is a part of tropospheric pollution).$(b)$ $HOCl_{(g)} \stackrel{h 
u}{\longrightarrow} \dot{O}H + \dot{Cl}$ is a reaction involved in the depletion of the ozone layer,so $(b)-(iii)$.$(c)$ $CaCO_{3} + H_{2}SO_{4} ightarrow CaSO_{4} + H_{2}O + CO_{2}$ is the reaction of acid rain with marble/limestone,so $(c)-(i)$.$(d)$ $NO_{2(g)} \stackrel{h 
u}{\longrightarrow} NO_{(g)} + O_{(g)}$ is a key step in the formation of photochemical smog,so $(d)-(ii)$.Thus,the correct sequence is $(a)-(iv), (b)-(iii), (c)-(i), (d)-(ii)$.

List-$I$	List-$II$
$(a)$ $2 SO_{2(g)} + O_{2(g)} \rightarrow 2 SO_{3(g)}$	$(i)$ Acid rain
$(b)$ $HOCl_{(g)} \stackrel{h \nu}{\longrightarrow} \dot{O}H + \dot{Cl}$	$(ii)$ Smog
$(c)$ $CaCO_{3} + H_{2}SO_{4} \rightarrow CaSO_{4} + H_{2}O + CO_{2}$	$(iii)$ Ozone depletion
$(d)$ $NO_{2(g)} \stackrel{h \nu}{\longrightarrow} NO_{(g)} + O_{(g)}$	$(iv)$ Tropospheric pollution
