Chapter 8, Problem 63P

(a)

Interpretation Introduction

Interpretation:

The number of possible linear dienes for the given compound with the molecular formula ${\text{C}}_{\text{6}}{\text{H}}_{\text{10}}$ has to be identified.

Concept Introduction:

Conjugated diene:

The molecular structure with alternative double bonds known as conjugated diene.

Isolated diene:

The molecular structure having two double bonds separated by more than one single bond is also known as isolated diene or non-conjugated dienes

Resonance Contributor:

The proper structure with the localized electrons is called a resonance contributor, a resonance structure, or a contributing resonance structure.

Delocalized electrons:

The sharing of electrons between two or more atoms is known as delocalization of electrons.  In order to have delocalized electrons, the system must be planar and have an alternative double bonds and single bonds.

Resonance hybrid:

The actual structure with delocalized electrons is called a resonance hybrid.
