5. Consider a planar SiH4 molecule.
(a) What is its point group symmetry?
(b) How many
ligand group orbitals (LGOs) are there for this molecule? Determine the symmetry of each LGO.
(c) What are the symmetries of the valence orbitals on sulfur?
(d) Construct a molecular orbital energy diagram for planar SiH4. Place the valence electrons in the diagram.
(e) Do you expect planar SiH4 to be stable? Why or why not?
(f) According to VSEPR, what is the shape you expect for SiH4?
