Question

Consider a planar SiH4 molecule.

(a) Construct a molecular orbital energy diagram for PLANAR SiH4.

Place the valence electrons in the diagram.

(b) Do you expect planar SiH4 to be stable? Why or why not?

planar SiH4 is unstable because silicon is larger in size and there are four hydrogen to form bond, there is steric replusion so they tend to move farther and form tetraheral to increase the bond angle to 109 degree 28 min
