Chapter 8.3, Problem 44PP

Interpretation Introduction

Interpretation:

The Lewis structure of ${\text{SO}}_2$ needs to be drawn.

Concept introduction:

Lewis structure can be shown by each atom in the molecule using the chemical symbol with the electrons. The bond is formed by sharing of valence electrons between the atoms and excess electron is shown as lone pair.

Answer to Problem 44PP

Explanation of Solution

First write the Lewis dot structure of ${\text{SO}}_2$ as sulfur has $6$ valence electron and oxygen also has $6$ valence electrons.

Lewis structure

Resonance structure is two or more possible of structure of the compound. The structure have similar geometry but have different arrangement of the electrons.

As in case of ${\text{SO}}_2$

More is the resonating structure, more will be the stability.

Conclusion

Lewis resonating structure is the different arrangement of electron with similar geometry.
