Canvas Classes · Accepted Answer

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

Step 1: Analyze each ion
- (i) :  (),  is weak field  high-spin ().
- (ii) :  (),  is strong field  low-spin ().
- (iii) :  (),  is weak field, tetrahedral  ().
- (iv) :  (), regardless of field strength  ().

Step 2: Order by decreasing

(i)  (iii)  (iv)  (ii)
