Chapter 16, Problem 16.39P

Interpretation Introduction

Interpretation: The possible stereoisomers of $\text{hepta}-2,4-\text{diene}$ is to be drawn and each double as $E$ or $Z$ is to be labeled.

Concept introduction: Stereochemistry is defined as the arrangement of molecule in three dimensional and its impact on chemical reactions. The prefix $E$ and $Z$ depends upon the location of the higher priority groups. When two higher priority groups are present on the opposite side then it is an $E$ isomer, whereas when two higher priority groups are present on the same side then it is a $Z$ isomer.
