Chapter 9, Problem 115IE

(a)

Interpretation Introduction

To determine: The value of $\text{X}-\text{P}-\text{X}$ bond angle predicted by the VSEPR model if all the electron-domains are of equal size.

(b)

Interpretation Introduction

To determine: The general trend in $\text{X}-\text{P}-\text{X}$ bond angle when the electronegativity of halogens increases.

(c)

Interpretation Introduction

To determine: The observed trend in $\text{X}-\text{P}-\text{X}$ bond angle as the electronegativity of $\text{X}$ changes on the basis of VSEPR model.

(d)

Interpretation Introduction

To determine: The structure of ${\text{PBrCl}}_{\text{4}}$ on the basis of the answer in part (c).
