The value of 'spin only ' magnetic moment for one of the followingconfiguration is 2.84 BM. Thecorrect one is

Answer»

`d^(4)` in strong ligand field)
`d^(4)` ( in weak ligand field
`d^(3)` ( in weak as well as strong fields)
`d^(5)`( in strong ligand field )

Solution :`mu=sqrt(n(n+2))=2.84BM` MEANS n=2. Only `d^(4)` in strong field can have TWO UNPAIRED electrons.
