Chapter 21, Problem 74E

(a)

Interpretation Introduction

Interpretation: The systematic name of $\text{isoprene}$ and the structures of the given polymers with configuration about the carbon-carbon double are to be drawn.

Concept introduction: Polymers are very large molecules having high molecular masses, hence are also called as macromolecules. The structure of polymers consists of a very large number of repeating units joined together through covalent bonds in a regular fashion. Isoprene is the repeating unit in natural rubber.
