The spin only magnetic moment of Mn ⁴⁺ ion is nearly

Options

  1. A3 BM
  2. B6 BM
  3. C4 BM
  4. D5 BM

Correct answer

C. 4 BM

Step-by-step solution

The electronic configuration of Mn is gathered ₂₅ Mn =[ Ar ] 3 ~d ⁵ 4 ~s ² Mn ⁴⁺=[ Ar ] 3 ~d ³ gathered Thus, three unpaired electrons are present. Spin only magnetic moment, = n(n+2) n=3 aligned &= 3(3+2) &= 15 =3.87 aligned =4 BM
