Chapter 7, Problem 7.102PAE

Interpretation Introduction

Interpretation: Both ozone ${\text{O}}_{\text{3}}$ and oxygen ${\text{O}}_{\text{2}}$

absorbs UV light in the upper atmosphere. However, the ozone absorbs slightly longer wavelength of UV light − wavelengths that would otherwise reach the surface of the planet. Based on this fact, the answers for following should be explained:

1. How can Lewis structure helps explain the bonding difference between ozone and oxygen that gives rise to the difference in the absorption wavelength.
2. What relationship or relationships between light and energy do you need to know to understand this photochemical application of Lewis structures.

Concept Introduction:

Lewis structure is representation of bonding electrons and lone pair of electrons in a molecule. For an atom, it represents the number of valance electrons present in it. The bonding is represented by drawing a line between the atoms that shows the shared pair of electron and lone pairs are dots around the atom symbol of the element.
