Stereoisomers as Reactants We are often interested in the differences in reactivity of various chemical compounds. Usually, we express the differences in reactivity in terms of the rates of the reactions. How is the rate of a reaction related to the energies of the reactant, the transition state, and the product? We can make several generalizations about rates of reactions involving various stereoisomers. Can you explain why each of these generalizations is true? Compounds that are diastereomers may react at different rates with any reagents. Compounds that are enantiomers must react at the same rate with achiral reagents. Compounds that are enantiomers may react at different rates with chiral reagents. Reading : Section 7.7 Chemistry S-20ab Week 2 91

Stereoisomers as Products Determine the product of the following reaction: H 2 , Pt Is the product chiral or achiral? Are the reactants and reagents chiral or achiral? We can make several generalizations about reactions that form stereoisomeric products.
