Chapter 9, Problem 92RQ

Hydrogen selenide is one of nature's most foul-smelling substances. Molecules of ${\text{H}}_{\text{2}}\text{Se}$ have H—Se—H bond angles very close to $90°$. How would VB theory explain the bonding in ${\text{H}}_{\text{2}}\text{Se}$? Use sketches of orbitals to show how the bonds are formed. Illustrate with appropriate orbital diagrams as well.
