This in class activity will walk students through a more advanced example for MO diagram generation from scratch. The students will work through the symmetry, point group, character table, and MO diagram of PH2F3.
To reinforce the comprehensive process for generating an MO diagram of a more complex example, PH2F3.
Determine shape from VSEPR theory
Find symmetry elements
Determine the point group
Find classes for each symmetry element
Generate the appropriate character table
Determine the MO diagram in two steps, 1) the PH2 part; then combining the PH2 MO with the F3 SALCs.
