Spin only magnetic moment of an octahedral complex of Fe 2 + in the presence of a strong field ligand in BM is:

Options

  1. A4 . 89
  2. B2 . 82
  3. C0
  4. D3 . 46

Correct answer

C. 0

Step-by-step solution

In presence of SFL Δ 0 > P means pairing occurs therefore ∴ No of unpaired e - ( s ) = 0 ∴ μ = n ( n + 2 ) BM = 0 [ n = No of unpaired e - ( s ) ]
