Chapter 11.5, Problem 11P

Interpretation Introduction

Interpretation:

The types of carbon-carbon double bonds, in each of the given substances, are to be identified.

Concept Introduction:

>

In conjugated dienes, the two carbon-carbon double bonds are joined by a single bond and have a unit $\text{C=C-C=C}$

>

In isolated dienes, the two or more carbon-carbon double bonds are separated from each other by one or more ${\text{sp}}^3$ hybridized carbon atoms.

>

In cumulated dines (also called as cumulenes) the two carbon-carbon double bonds share a single carbon and have a unit $\text{C=C=C}$.
