Question
Chapter SRP, Problem 8P
Interpretation Introduction
Interpretation:
The structure of the product(s) formed in the Diels-Alder reaction of cyclopentadiene with ethene at the given temperature is to be written.
Concept Introduction:
In a Diels-Alder reaction, dienophile is reacted with a conjugated diene. Such reactions are called pericyclic reactions. In this reaction, two π-bonds are converted to two new stronger σ-bonds.

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?
Two substitution products result from the
reaction between 3-chloro-3-methyl-1-
butene with sodium acetate (CH3COO – Na +)
in acetic acid under SN1.
Identify the products.
Write a general rule that can be used to predict the major product of a Diels–Alder reaction between an alkene with an electron-withdrawing substituent and a diene with a substituent that can donate electrons by resonance depending on the location of the substituent on the diene.
