Select the correct order of magnetic moment (inBM) from the folliwng options
(I) `[MnCI_(4)]^(2-)` (II) `[CoCI_(4)]^(2-)`
(III) `[Fe(CN)_(6)]^(4-)` .

A

`IgtIIgtIII`

B

`IIIgtIIgtI`

C

`IIIgtIgtII`

D

`IgtIIIgtII`

Text Solution

Verified by Experts

The correct Answer is:
A
`[MnCI_(4)]^(2-): Pgtdelta_(t), d^(7)-` system
`("weak field ligand") (n =3) mu_(eff) = 3.89 BM`
`[Fe(CN)_(6)]^(4-): PltDelta_(0), d^(6)`-system
(strong field ligand) `(n =0) mu_(eff) = 0BM` .
