Question
Chapter 8.7, Problem 11P
Interpretation Introduction
Interpretation:
- The relative stabilities of cumulated, conjugated, and isolated dienes to be investigated.
Concept Introduction:
Isolated Diene: Hydrocarbons with two double bonds; which separated by more than one single bond.
Conjugated diene: Dienes are hydrocarbons with two double bonds; where the conjugated double bonds are separated by one single bond.
Allenes (cumulated double bonds): The hydrocarbons that have double bonds adjacent to one another.

Use a sheet of paper and draw structures for all the isolated, conjugated, and cumulated dienes of molecular formula C5Hg.
Chlordane, like DDT, is an alkyl halide that was used as an insecticide for crops such as corn and citrus and for lawns. In 1983, it was banned for all uses except against termites, and in 1988, it was banned for use against termites as well. Chlordane can be synthesized from two reactants in one step. One of the reactants is hexachlorocyclopentadiene. What is the other reactant?
3. The heat of hydrogenation for allene, H½C = C= CH2, to yield propane is – 295
kJ/mol, and the heat of hydrogenation for a typical monosubstituted alkene such as
propene is -126 kJ/mol. Is allene more stable or less stable than you might expect
for a diene ? Explain.
