The value of 'spin only' magnetic moment...

The value of 'spin only' magnetic moment for one of the following configuration is `2.84B.M.` The correct one is:

A

`d^(5)` (in strong field ligand)

B

`d^(3)` (in weak as well as strong field ligand)

C

`d^(4)` (in weak field ligand)

D

`d^(4)` (in strong field ligand)

Text Solution

Verified by Experts

The correct Answer is:
D
The given value of `mu` (spin only)
`2.84=sqrt(n(n+2))GM`, So, n = 2
Among the given configurations, `d^(4)` system in strong field ligand will have 2-unpaired `e^(-)` in `t_(2g)` set of orbitals as shown below.
