Use the concepts of crystal field theory to predict the highest-energy orbital or group of orbitals among the five d orbitals when a transition metal ion is placed in the following type of ligand field environments (assuming conventional axes definition is used) Draw the geometry and draw the highest energy orbital (label: axis and orbital) to show how your came to your conclusion. Square planar: Trigonal bipyramidal:

In any energy level, what is the maximum number electrons of a group of p-orbitals can hold? (This is referring to all of the possible orientations when referring to the group, not just one orientation.) Your Answer:

Select the correct statement for energy level n=9 Each of the d orbitals have different energy b) All three p orbitals have the same energy because they are degenerate The two s orbitals have the same energy because they are degenerate d) There are a total of 81 electrons at n=9

The combination of a p_z orbital and the out-of-phase LGO of two s orbitals yields a sigma bonding molecular orbital when the atoms are in a linear arrangement (first figure below, also see H-Be-H). in a bent arrangement like you might find in H_2O, this combination of orbitals yields a higher energy, and therefore, less stable molecular orbital (second figure below.) a) Why is the linear arrangement of these orbitals more stable than the bent arrangement? b) If the bond...

1. a) In the higher periods of the periodic table, there is more mixing between s and p orbitals. Without doing detailed calculations, it may not be clear whether Cl2 has “significant" mixing. Draw molecular orbital diagrams for this molecule (valence orbitals only!) for both the “significant mixing” and “insignificant mixing” cases. Can you distinguish which of these is the correct diagram based on magnetic properties of the molecule? Why or why not? b) Draw a molecular orbital energy diagram...
