Match List-I with List-II:
| List-I (Molecule/Ion) | List-II (Total Shared Electron Pairs) | ||
|---|---|---|---|
| A | \( \text{H}_2 \) | I | 4 |
| B | \( \text{O}_2 \) | I | 1 |
| C | \( \text{N}_2 \) | III | 2 |
| D | \( \text{CO}_3^{2-} \) | IV | 3 |
Choose the correct answer from the options given below:
Correct answer · Option 4
A-(II), B-(III), C-(IV), D-(I)
Explanation
H2 shares 1 pair (single bond), O2 shares 2 pairs (double bond), N2 shares 3 pairs (triple bond), and CO3^2- has 4 shared pairs (one double bond and two single bonds).
