Chapter 5, Problem 5.35P

For the molecule ${\text{PCl}}_{\text{5}}$ :
a. Using the character table for the point group of ${\text{PCl}}_{\text{5}}$ determine the possible type(s) ofhybrid orbitals that can be used by P in forming $\sigma$ bonds to the five Cl atoms.
b. What type(s) of hybrids can be used in bonding to the axial chlorine atoms? To theequatorial chlorine atoms?
c. Considering your answer to part b, explain the experimental observation that the axial $\text{P}—\text{Cl}$ bonds (219 pm) are longer than the equatorial bonds (204 pm).
The following problems require the use of molecular modeling software.
