Worksheet: Hybridization in Transition Metal Complexes
In this worksheet, we will practice defining hybrid orbitals and assigning the hybridization of transition metals based on their electron pair geometries.
According to valence bond theory, what is the difference between a complex with d2sp3 hybridization and another with sp3d2 hybridization?
- AThe complex having d2sp3d2 hybridization does not exist; the electrons must fill the orbitals with the same principal quantum number.
- BThere is no actual difference; the orbitals involved are the same, only listed in a different order.
- CThe complex having d2sp3 hybridization is an outer-shell complex, while the complex with sp3d2 hybridization is an inner-shell complex.
- DThe complex having sp3d2 hybridization does not exist; the electrons must fill the lowest energy orbitals first.
- EThe complex having d2sp3 hybridization is an inner-shell complex, while the complex with sp3d2 hybridization is an outer-shell complex.
The size of the crystal field splitting in octahedral transition metal complexes only influences the electronic configuration when there is a choice between pairing electrons in the t2g orbitals and half-filling the eg orbitals. Which of the following d subshell occupancies allows for high-spin and low-spin octahedral complexes with different electronic configurations?
