Chapter 9, Problem 56E

Interpretation Introduction

Interpretation:

On the basis of Lewis structure, the ${\text{Br}}_{\text{3}}^{-}$ and ${\text{I}}_3^{-}$ ion being stable while ${\text{F}}_3^{-}$ not being stable is to be explained.

Concept introduction: The Lewis structure is a method of representation of the bonds and the number of lone pair electron in a molecule.

To determine: An explanation for ${\text{Br}}_{\text{3}}^{-}$ and ${\text{I}}_3^{-}$ ion being stable while ${\text{F}}_3^{-}$ not being stable.
