Match List-I with List-II:
| List-I | List-II | ||
|---|---|---|---|
| i | \( 2\text{SO}_{2(g)} + \text{O}_{2(g)} \longrightarrow 2\text{SO}_{3(g)} \) | a | Acid rain |
| ii | \( \text{HOCl}_{(g)} \xrightarrow{h\nu} \dot{\text{O}}\text{H} + \dot{\text{C}}\text{l} \) | b | Smog |
| iii | \( \text{CaCO}_3 + \text{H}_2\text{SO}_4 \longrightarrow \text{CaSO}_4 + \text{H}_2\text{O} + \text{CO}_2 \) | c | Ozone depletion |
| iv | \( \text{NO}_{2(g)} \xrightarrow{h\nu} \text{NO}_{(g)} + \text{O}_{(g)} \) | d | Tropospheric pollution |
Choose the correct answer from the options given below.
Correct answer · Option 4
i – a, ii – b, iii – c, iv – d
Explanation
Matchings: (i) SO2 oxidation leads to acid rain (a), (ii) HOCl photolysis causes ozone depletion (c), (iii) CaCO3 with H2SO4 causes stone leprosy/acid rain effects mapped to tropospheric/acid rain components, (iv) NO2 photolysis causes smog/tropospheric pollution (d). Correct pairing gives option (4).
