(a)

Interpretation Introduction

Interpretation:

The electrons group arrangement and ideal bond angle around the central atom in structure (a) are to be determined. Also, the deviation from the ideal bond 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.
