Question

Canvas Classes · Accepted Answer

Strategy:
 A species that responds to an external magnetic field is paramagnetic, implying it has one or more unpaired electrons. Check the d-electron count and ligand field for each.

Step 1: Evaluate each complex
- :  () + weak field  high spin  5 unpaired  Paramagnetic.
- :  () + strong field  square planar  0 unpaired  Diamagnetic.
- :  () + strong field  low spin  0 unpaired  Diamagnetic.
- :  ()  0 unpaired  Diamagnetic.
