Magnetic moment `sqrtn (n+2)BM` (where n = No. unpaired electrons) .
The value of of spin only magnetic moment for octahedral complex of the following configuration is `2.84BM` The correct statement is
(a) `d^(4)` (in weak field ligand)
(b) `d^(2)` (in weak field and in strong field ligand)
(c) `d^(3)` (in weak field and in strong field ligand)
(d) `d^(5)` (in strong field ligand) .

The value of 'spin only' magnetic moment for one of the following configurations, is `2.84 BM`. The ćorrect one is : `d^4` (in strong ligand field) , `d^2` (in weak ligand fteld) , `d^3` (in weak as well as strong fields) , `d^5` (in strong ligand field)
