Chapter 10, Problem 10.41P

(a)

Interpretation Introduction

Interpretation:

The shape and ideal angle around the central atom in ${\text{ClO}}_3^{-}$ molecule are to be determined. Also, the deviation from the ideal angle is to be explained.

Concept introduction:

The steps to determine the molecular shape of a given molecule are as follows:

Step 1: Write the Lewis structure of the given formula and place the atoms.

Step 2: Count all electron groups including bonding and non-bonding pairs around the central atom and use it to assign one of the five electron-group arrangement.

Step 3: Write the ideal bond angle related to the electron-group arrangement and the effect of any deviation can be predicted by using VSEPR.

Step 4: Count the bonding and non-bonding electron groups and draw the molecular shape accordingly.
