Question
What will be the theoretical value of ′spin only′ magnetic moment when Fe(SCN)3 reacts with a solution containing F- ions to yield a colourless complex ?
Options
A.2.83 B.M.
B.3.87 B.M
C.5.92 B.M.
D.1.73 B.M.
Solution
[Fe(SCN)(H2O)5]2+ 
[FeF6]3-, F- being weak ligand Fe3+ - 
. Therefore, five
unpaired electrons and so μ =
B.M. ≈ 5.92.
