Chapter 5, Problem 5.40AP

Interpretation Introduction

(a)

Interpretation:

The product obtained upon the ozonolysis of natural rubber, followed by reaction with ${\text{H}}_{\text{2}}{\text{O}}_{\text{2}}$ is to be stated.

Concept introduction:

Ozonolysis is a reaction in which the carbon-carbon double bonds undergoes oxidative cleavage with the action of ozone $\left({\text{O}}_{\text{3}}\right)$ and gives oxidized products. For example ozonolysis of alkenes give carbonyl compounds and the ozonolysis of azo compounds give nitrosamines. Ozonolysis is a two step process. In the primary step, the reaction of alkenes and ozone forms an addition product known as ozonide. In the next step, the ozonide will react with the oxidizing agents to form the desired product.

Interpretation Introduction

(b)

Interpretation:

The suggestion for the structure of gutta-percha which gives the same ozonolysis product as the natural rubber give is to be stated.
