Chapter 20.1, Problem 20.1P
Interpretation Introduction

Interpretation: Among the given terpenes, the one that contain conjugated double bonds has to be found.

Concept Introduction:

Dienes:

Dienes are organic compounds that contain two double bonds. In the name “di”-means “two” and “ene”- means from the word alkene which is a double bond characteristic functional group.

Types of Dienes:

Conjugated Dienes are those compounds in which the two double bonds are separated by a single bond.

Unconjugated Dienes are those compounds in which the two double bonds are separated by two or more single bonds.

Cumulated Dienes are those compounds in which the two double bonds are shared by a sp- hybridised carbon atom.

Predict the major products of the following organic reaction: O O + A ? Some important notes: • Draw the major product, or products, of the reaction in the drawing area below. • If there aren't any products, because no reaction will take place, check the box below the drawing area instead. • Be sure to use wedge and dash bonds when necessary, for example to distinguish between major products that are enantiomers.
