Canvas Classes · Accepted Answer

Strategy:
 Determine the electron configurations within an octahedral field for each complex to find which lack unpaired electrons.

Step 1: Determine the configuration of each complex
- A. :  (). Strong field  Low spin . Has 2 unpaired electrons. (Paramagnetic)
- B. :  (). Strong field  Low spin . Has 0 unpaired electrons. (Diamagnetic)
- C. :  (). Strong field  Low spin . Has 0 unpaired electrons. (Diamagnetic)
- D. :  (). Weak field ( and )  High spin . Has 4 unpaired electrons. (Paramagnetic
