Question

Aldrin, a chlorinated insecticide now banned from use in the United

States, can be made by Diels–Alder reaction of hexachloro-1,3-cyclopentadiene with norbornadiene. What is the structure of aldrin?

Step-by-Step Solution

Verified

Answer

The structure of aldrin is:

1Diels-Alder reaction

The Diels-Alder reaction is an important organic chemical reaction discovered by German chemists Otto Diels and Kurt Alder in the year 1928.

It is type of reaction in which the reactant include a substituted alkene and conjugated diene. This substituted alkene commonly referred to as dienophile.

The Diels-Alder reaction proceed via concerted mechanism in which bond breakage and bond formation occurs in a single step.

2Formation of aldrin by Diels-Alder reaction

Diels–Alder reaction of hexachloro-1,3-cyclopentadiene with norbornadiene to give Aldrin, a chlorinated insecticide now banned from use in the United States.
