The value of the ‘spin only’ magnetic moment for one of the following configurations is 2.84 BM. The correct one is

Options

  1. Ad ^4 (in strong ligand filed)
  2. Bd ^4 (in weak ligand filed)
  3. Cd ^3 (in weak as well as in strong fields)
  4. Dd ^5 (in strong ligand filed)

Correct answer

A. d ^4 (in strong ligand filed)

Step-by-step solution

d ^4 in strong field, so unpaired electrons = 2.
