Answer #1

The reaction of cyclopentadiene and maleic anhydride will be Diels Alder reaction

It will form the following exo and endo form of the adduct.

The side products will be formed by addition of cyclopentadiene with cyclopentadiene to form dicyclopentadiene

The dicyclopentadiene can be endo or exo so two side products will be obtained.

The IR peaks will show the following characteristics

The shifting of Ir peak of carbonyl group due to absence of conjugation in product will explain its formation

The peaks will be near 1840 cm-1 (Carbonyl peak)

Also near 1760cm-1

In STEREOCHEMISTRY OF BROMINE ADDITION experiment, we got the product 1) only the syn enantiomers, 2) only the anti enantiomers, or 3) a mixture of diastereomers bycotton. Then we weigh the product and take the melting point. Determine which stereoisomers of 2,3-dibromo-3-phenylpropanoic acid were formed and propose a mechanism for the reaction. we don’t crystallize the final product. This means that your final product might be slightly impure. Why will this not affect your mechanistic analysis?
