Match the gases in List-I with their properties in List-II. List-I: (P) Carbon dioxide, (Q) Water vapour, (R) Ozone, (S) Sulphur dioxide List-II: (1) Greenhouse gas, (2) Linear molecule, (3) Non-linear molecule, (4) Responsible for acid rain, (5) Oxidizing agent

1. P -> 1,2; Q -> 1,3; R -> 1,3,5; S -> 3,4
2. P -> 1,2,4; Q -> 1,3; R -> 3,5; S -> 1,2,4
3. P -> 1,2; Q -> 1,3; R -> 1,5; S -> 1,2,5
4. P -> 1,2; Q -> 3; R -> 1,5; S -> 1,2,4

Correct answer: P -> 1,2; Q -> 1,3; R -> 1,3,5; S -> 3,4

Solution

CO2: linear + greenhouse (1,2). H2O vapour: non-linear + greenhouse (1,3). O3: non-linear + greenhouse + oxidizing agent (1,3,5). SO2: non-linear + acid rain (3,4). Best match is option A.
