Question
Chapter 11.6, Problem 12P
Interpretation Introduction
Interpretation:
Heats of combustion with the appropriate diene is to be matched.
Concept Introduction:
Heats of combustion is the amount of heat given off when one mole of a diene is burned completely.
The more stable the diene, the less the heat of combustion.
The conjugated diene is more stable than an isolated or cumulated diene while cumulated dienes are the least stable.

During an experiment involving conjugated dienes, some doubts arose when discussing the results obtained so far: (a) A student obtained two products from the reaction of 1,3-cyclohexadiene with Br2. His lab partner was surprised to get only one product from the reaction of 1,3 - cyclohexadiene with HBr. Explain these distinct results. (b) One student, seeing the discussion of colleagues, commented that she obtained two distinct products when reacting 1,3,5-hexatriene with HBr, with different yields just by changing the reaction temperature.
