Question
Chapter 14.SE, Problem 26AP
Interpretation Introduction
Interpretation:
The structures and names of the six possible diene isomers with molecular formula C5H8 are to be given. Further among them which are conjugated dienes is also to be stated.
Concept introduction:
Three are three types of dienes. They are cumulative, conjugated and isolated dienes. Cumulative dienes have two double bonds on adjacent carbon atoms. Conjugated dienes have the double bonds on alternate carbon atoms. In isolated double bonds the two double bonds are separated by more than one C-C single bonds.
To give:
The structures and names of the six possible diene isomers with molecular formula C5H8. Further to state among them which are conjugated dienes.
