According to molecular orbital theory, the number of unpaired electrons in  is

Canvas Classes · Accepted Answer

Step 1 — MO configuration of  (18 electrons):

Step 2 — Count unpaired electrons:
-  has 4 electrons filling both degenerate π orbitals completely (2 in each)
- All electrons are paired

Step 3 — Magnetic nature:
- 0 unpaired electrons → diamagnetic
