Answer #1

The qualitative molecular orbital diagram for the hypothetical square planar silane molecule(SiH4) can be drawn as shown below.

The bond order of SiH4 = (1/2) * 8 = 4 (since there are a total of 8 electrons)

The bond order of Si-H = 4/4 = 1 (since there are 4 H's)

Here, t2-level is the HOMO and t2* level is the LUMO.

The MO diagram for methane molecule (CH4) can be drawn as shown below.
