Chapter 3, Problem 3.34P

Interpretation Introduction

Interpretation: The species between ${\text{PF}}_4^{+}$ and ${\text{PF}}_{\text{3}}\text{O}$ that has smaller $\text{F}-\text{P}-\text{F}$ angleand the longer fluorine-fluorine distanceare to be stated.

Concept introduction: The molecular shape is determined primarily by the repulsions between pairsof electrons in the molecule or molecular ion. As per valence-shell-electron-pair repulsion theory, these pairs of electrons are bonding pairs or lone pairs. The valence-shell-electron-pair repulsion theory is abbreviated as VSEPR.
