Question

Calculate the spin only magnetic moment of k3[fe(cn)6]

Answer 1

Answer:

1.73

Explanation:

• As CN is a strong field ligand it will induce pairing of electrons in Fe3+ . Fe3+ will be d5 case and hybridisation of the compound will be d2sp3 Due to this one electron will be left unpaired and hence magnetic moment will be 1.73

! stands for spin

3d5 case= [!!] [!!] [! ][ ] [ ]

Answer 2

Answer:

$\sqrt{3}$

Explanation:

CN is strong field liand

so induces pairing of electrons in Fe
