Due to the Aufbau principle, the total spin of a coordination complex is determined by how much these orbitals are split. For 10 points each:
[10e] Name these five orbitals, one of which takes an electron from the 4s orbital in chromium and copper. These orbitals are partially filled in transition metals.
ANSWER: d orbitals [accept 3d orbitals]
[10m] The rates of transitions in coordination complexes are primarily governed by the spin selection rule and a rule named for this physicist, which forbids transitions between gerade ("geh-rah-deh") and ungerade ("oon-geh-rah-de") orbitals.
ANSWER: Otto Laporte [accept Laporte selection rule]
[10h] For ions with four, five, or six d-electrons, their total spin determines whether they have this kinetic property. Henry Taube found that outer orbital complexes have this property, which should not be confused with instability.
ANSWER: substitutional lability [or kinetic lability; or word forms like labile]
