Chapter 8, Problem 67P

a)

Interpretation Introduction

Interpretation:

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

Concept Introduction:

Conjugated diene: Two double bonds separated by a single bond is known as conjugated diene.

Isolated diene: Otherwise known as non-conjugated dienes; having two double bonds separated by more than one single bond.

Cumulated diene: two double bonds connected to a similar atom.

Resonance Contributor: The appropriate 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 known as delocalization of electrons.  In order to have delocalized electrons, the system must be planar and have alternative double bonds and single bonds.

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