Question

Canvas Classes · Accepted Answer

Odd-electron molecules have an odd total number of valence electrons, resulting in an unpaired electron.

Step 1 — Count valence electrons:

| Oxide | Valence electrons | Odd/Even |
|-------|------------------|----------|
|  | 2(5) + 6 = 16 | Even ✗ |
|  | 5 + 2(6) = 17 | Odd ✓ |
|  | 2(5) + 3(6) = 28 | Even ✗ |
|  | 2(5) + 5(6) = 40 | Even ✗ |

Step 2:  has 17 valence electrons → odd electron on N → paramagnetic
