(a)
Interpretation: The correct crystal field diagram for the given complex is to be identified.
Concept introduction: The electrons in the d orbital of a
To determine: If the given crystal field diagram for Zn(NH3)42+ is correct or not.
The given crystal field diagram for Zn(NH3)42+ is not correct.
(b)
Interpretation: The correct crystal field diagram for the given complex is to be identified.
Concept introduction: The electrons in the d orbital of a transition metal split into high and low energy orbitals when ligands are attached to it. The energy difference between these two levels depends upon the properties of both metal and the ligands. If the ligand is strong, then splitting will be high and the complex will be low spin. If the ligand is weak, then splitting will be less and the complex will be high spin.
To determine: If the given crystal field diagram for Mn(CN)63+ is correct or not.
