Chapter 5, Problem 5.18P

${\text{TaH}}_{\text{5}}$ has been predicted to have ${\text{C}}_{\text{4v}}$ symmetry, with a calculated axial $\text{H}—\text{Ta}—\text{H}$ angle ofapproximately 117.5°. Using the six-step approach described in Section 5.4.2, describe thebonding in ${\text{TaH}}_{\text{5}}$ on the basis of matching group orbitals and central atom orbitals according totheir symmetry.
