Match List-I with List-II:
| List-I (Chemical Species) | List-II (Octet Rule Deviation Category) | ||
|---|---|---|---|
| A | \( \text{BeH}_2 \) | I | Odd-electron molecule |
| B | \( \text{NO}_2 \) | II | Expanded octet (12 electrons around central atom) |
| C | \( \text{PF}_5 \) | III | Incomplete octet (4 electrons around central atom) |
| D | \( \text{SF}_6 \) | IV | Expanded octet (10 electrons around central atom) |
Choose the correct answer from the options given below:
Correct answer · Option 4
A-(III), B-(I), C-(IV), D-(II)
Explanation
BeH2 has an incomplete octet (4 electrons around Be). NO2 is an odd-electron molecule. PF5 has 10 electrons around P. SF6 has 12 electrons around S.
