a)

Interpretation Introduction

Interpretation:

The each C=C π system in each given compounds should be identified whether it is cumulated, conjugated or isolated.

Concept introduction:

The compounds having two C=C π bonds or C=C bond with C=O bonds are called dienes.

Based on the proximity of C=C bonds in dienes, they are classified into three.

  • Cumulated dienes: the C=C bonds are located adjacent carbons.
  • Conjugated dienes: the C=C bonds or C=C and C=O are separated by one σ-bond.
  • Isolated dienes: the C=C bonds are separated by two or more σ-bonds.
