Solution

Correct Answer:

5.92 BM

For spin-only magnetic moment, mu = sqrt(n(n+2)) BM, where n is number of unpaired electrons. For a high-spin d5 ion, n = 5. Hence mu = sqrt(5 x 7) = sqrt(35) = 5.92 BM (approximately). This value is consistent with strong paramagnetism expected for five unpaired electrons.
