Number of paramagnetic oxides among the following is

Question

Canvas Classes · Accepted Answer

Paramagnetic oxides contain unpaired electrons.

Step 1 — Analyse each oxide:

- : ionic, all electrons paired → diamagnetic ✗
- CaO: ionic, all electrons paired → diamagnetic ✗
-  (sodium peroxide): contains  (peroxide ion) with BO = 1, all paired → diamagnetic ✗
-  (potassium superoxide): contains  (superoxide ion) with 1 unpaired electron → paramagnetic ✓
- MgO: ionic, all electrons paired → diamagnetic ✗
- : ionic, all electrons paired → diamagnetic ✗

Step 2: Only  is paramagnetic → 1 oxide
