Textbook Question

Chapter 5, Problem 5.39SP

A graduate student was studying enzymatic reductions of cyclohexanones when she encountered some interesting chemistry. When she used an enzyme and NADPH to reduce the following ketone, she was surprised to find that the product was optically active. She carefully repurified the product so that no enzyme, NADPH, or other contaminants were present. Still, the product was optically active.

Chapter 5, Problem 5.39SP, A graduate student was studying enzymatic reductions of cyclohexanones when she encountered some

a. (a) Does the product have any asymmetric carbon atoms or other stereocenters?
b. (b) Is the product capable of showing optical activity? If it is, explain how.
c. (c) If this reaction could be accomplished using H₂ and a nickel catalyst, would the product be optically active? Explain.

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone
