between Fe+2 and Fe+3 which one is more stable?Calculate the value of magnetic moment of the stable ion.
Answers
Answer:
Explanation:
Fe3+ ion is more stable due to its half-filled 3d5 electron configuration. As half filled and completely filled shells are more stable Fe3+ ion is more stable. While Fe2+ is not stable.
the 'spin only' magnetic moment of M2+(aq) ion (Z = 27). ... Spin only magnetic moment == 3.87 B.M. ... So metal will tend to form tetrahedral structure, carrying 3 unpaired electrons in t2g.So spin only magnetic moment would be √(3(3+2)) = √15 = 3.87.
However, the spin-only magnetic moment survives in all cases and is related to the total number of unpaired electrons. ] has a magnetic moment of 2.3 B.M., which is a d5 low-spin complex with one unpaired electron. ]3+ ions are high-spin with 5 unpaired electrons. It has a magnetic moment of 6 B.M
Hey dear,
● Explaination -
I) Fe3+ is more stable than Fe2+.
II) For Fe2+,
No of free electrons = 4
Magnetic moment
MM = √(4×6) = 4.89 BM
For Fe3+,
No of free electrons = 5
Magnetic moment
MM = √(5×7) = 5.92 BM
Hence, magnetic moment of Fe2+ is 4.89 BM & that of Fe3+ is 5.92 BM.
Hope this helps you. Thanks for asking..
