Canvas Classes · Accepted Answer

Strategy:
 Calculate the number of unpaired electrons () for each complex to order their spin-only magnetic moments.

Step 1: Analyze each ion
- :  (), strong field  low spin  1 unpaired electron.
- :  (), strong field  low spin ()  2 unpaired electrons.
- :  (), weak field  high spin ()  4 unpaired electrons.
- :  (), weak field  (tetrahedral)  high spin  5 unpaired electrons.

Step 2: Order by increasing
