Chapter 8.3, Problem 45PP

Interpretation Introduction

Interpretation:

The Lewis structure of ${\text{O}}_3$ 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 45PP

Explanation of Solution

First the Lewis dot structure of ${\text{O}}_3$ oxygen has $6$ valence electron in the outermost shell.

Lewis structure

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

As in case of ${\text{O}}_3$ :

More is the resonating structure, less is the energy and more stable is the molecule.

Conclusion

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