Chapter 9, Problem 9.8VP

Interpretation Introduction

Interpretation: The $\text{F}-\text{M}-\text{F}$ bond angle in ${\text{MF}}_8{}^{2-}$ is to be predicted if the geometry of the anion is cubic.

Concept introduction: The angle formed between the two bonding atoms is known as bond angle. It is the angle between three or at least two atoms. When two atoms shared electrons pair with each other in an equal extent then the bond is non polar in nature but when a pair of electrons is unequally shared between two atoms then a polar chemical bond is formed.

To determine: The $\text{F}-\text{M}-\text{F}$ bond angle in ${\text{MF}}_8{}^{2-}$ if the geometry of the anion is cubic.
