Concept explainers
(a)
Interpretation: The diene that has the larger heat of hydrogenation is to be identified.
Concept introduction: Diene is a hydrocarbon that contains two
Conjugated diene consists of two double bonds that are separated by a single bond, whereas isolated diene also consists of two double bond but they are separated by two more carbon atoms.
The example that shows the basic difference between conjugated diene and isolated diene is shown below.
Figure 1
The stability of conjugated diene is more than isolated diene. Due to which the heat of hydrogenation is smaller for conjugated diene, whereas heat of hydrogenation for isolated diene is larger.
