Chapter 25, Problem 25.83QP

(a)

Interpretation Introduction

Interpretation:

The geometry of the given set of substances by VSEPR theory has to be given.

Concept introduction:

VSEPR theory: Valence shell electron pair repulsion theory.  Repulsion between bonding electrons and lone pair electrons are the basis of this theory.

$\begin{array}{l}\text{Repulsion of electrons in a molecule is given below}\\ \text{Lone}\text{pair-Lone}\text{pair}>\text{Lone}\text{pair-Bonding}\text{pair}>\text{Bonding}\text{pair-}\text{Bonding}\text{pair}\end{array}$

To give: The geometry of ${\text{I}}_{\text{3}}{}^{\text{-}}$ molecule by VSEPR theory
