Identify the ion (hydrated in solution) which is not correctly matched with its spin only magnetic moment (in BM) given in brackets:
Identify the ion (hydrated in solution) which is not correctly matched with its spin only magnetic moment (in BM) given in brackets:
Show Hint
When dealing with transition metal ions, calculate the number of unpaired electrons based on the oxidation state to predict the expected magnetic moment.
Updated On: Jun 6, 2025
- Cr³⁺ (4.90)
- Cu²⁺ (1.73)
- Co³⁺ (4.90)
- Fe³⁺ (4.90)
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Fe³⁺ ion should have a magnetic moment of 5.92 BM (for 5 unpaired electrons), while it is given as 4.90 BM, making this match incorrect.
