Question
Chapter 16, Problem 16.40P
Interpretation Introduction
Interpretation: The given diene is to be ranked in increasing order of heat of hydrogenation.
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.

Rank the following radicals in order of increasing stability.
Furan and maleimide undergo a Diels–Alder reaction at 25 °C to give the endo isomer of the product. When the reactiontakes place at 90 °C, however, the major product is the exo isomer. Further study shows that the endo isomer of theproduct isomerizes to the exo isomer at 90 °C.furan: O maleimide:OON H(a) Draw and label the endo and exo isomers of the Diels–Alder adduct of furan and maleimide.(b) Which isomer of the product would you usually expect from this reaction? Explain why this isomer is usually favored.(c) Examine your answer to (b) and determine whether this answer applies to a reaction that is kinetically controlled orone that is thermodynamically controlled, or both.(d) Explain why the endo isomer predominates when the reaction takes place at 25 °C and why the exo isomer predominates at 90 °C
