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.

Q1:

According to valence bond theory, what is the difference between a complex with d2sp3 hybridization and sp3d2 hybridization?

  • AThe complex having d2sp3 hybridization is an “outer shell” complex, while the complex with sp3d2 hybridization is an “inner shell” complex.
  • BThere is no actual difference; the orbitals involved are the same, only listed in a different order.
  • CThe complex having sp3d2 hybridization does not exist; the electrons must fill the lowest energy orbitals first.
  • DThe complex having d2sp3 hybridization is an “inner shell” complex, while the complex with sp3d2 hybridization is an “outer shell” complex.
  • EThe complex having d2sp3d2 hybridization does not exist; the electrons must fill the orbitals with the same principal quantum number.
