Question

Based on the melting point and specific rotation experimental data:

a.draw the structure(s) of the product(s) of the trans-cinnamic acid addition reaction with bromine.

b. State whether the addition of Br2followed asyn or antiaddition or both. Give reasons.

c. Is this product chiral? If so, identify the chirality centers.

d. Is the product of the trans-cinnamic acid addition reaction with bromine optically active? Give reasons.

e. Is your answer to Question 2d what you expected? Give reasons.

f. What is the enantiomeric excess of your product of the trans-cinnamic acid addition reaction with bromine?

g.Can optically inactive reactants make optically active products?

Explanation / Answer

b. the addition of Br2 followed antiaddition.

c. product is chiral at both the Br attached carbons.

d. the product of the trans-cinnamic acid addition reaction with bromine optically active because achiral carbon is converted to chiral carbon.

g. Can optically inactive reactants make optically active products? answer = No. if the reagent is optically active then the product may be optically active.
