Chapter 5, Problem 39E

Interpretation Introduction

Interpretation:

The effect of the structure of ozone on the amount of UV light hitting the earth is to be explained.

Concept Introduction:

Ozone is an atmospheric gas that absorbs UV light and thus, protects life on Earth from excessive UV exposure.

The reaction takes place as follows:

${\text{O}}_{\text{3}}+\text{ UV light }\to {\text{ O}}_2+\text{ O}$

Ozone absorbs UV light and the oxygen-oxygen bond breaks.
