Question

Canvas Classes · Accepted Answer

Strategy:
 A spin-only magnetic moment of 5.9 BM corresponds to 5 unpaired electrons ().

Step 1: Evaluate the options
- :  () strong field  square planar, 0 unpaired.
- :  () weak field  tetrahedral, 2 unpaired.
- :  ()  tetrahedral, 0 unpaired.
- :  (). With weak field  in a tetrahedral geometry, the splitting is minimal. Electrons remain unpaired conforming to Hund's rule.   5 unpaired electrons.
