Question:
The hexaquo manganese(II) ion contains five unpaired electrons, while the hexacyanoion contains only one unpaired electron. Explain using Crystal Field Theory.

Answer:

[Mn(H₂O)₆]²⁺ [Mn(CN)₆]^4-

Mn is in the +2 oxidation state. Mn is in the +2 oxidation state.

The electronic configuration is d^5. The electronic configuration is d⁵.

The crystal field is octahedral. Water is a weak field ligand. Therefore, the arrangement of the electrons in [Mn(H₂O)₆]²⁺ is t2g3eg2.
The crystal field is octahedral. Cyanide is a strong field ligand. Therefore, the arrangement of the electrons in [Mn(CN)₆]^4-is T2g5eg0.

Hence, hexaaquo manganese (II) ion has five unpaired electrons while hexacyano ion has only one unpaired electron.
