FREE Expert Solution
We have to determine the number of unpaired electrons in each of the given complexes.
The number of unpaired electrons in a complex can be determined through:
- Calculating the oxidation number of metal. This gives the number of electrons in the d orbital.
- Finding out whether the ligand attached to the metal is a strong-field or a weak-field ligand.
- Filling the d electrons of the metal into the split d orbitals to find out how many are unpaired.
