- 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. If this reaction could be accomplished using H2 and a nickel catalyst, would the product be optically active? Explain.arrow_forwardComplete the following reactions: please answer them all with explanations, thank you!arrow_forward3b)Give the mechanisms for the following transformations:arrow_forward
- Nonconjugated , -unsaturated ketones, such as 3-cyclohexenone, are in an acid-catalyzed equilibrium with their conjugated , -unsaturated isomers. Propose a mechanism for this isomerization.arrow_forwardIn an advanced synthetic chemistry experiment, a researcher prepares a compound, ZY-7, by reacting a ketone (C5H10O) with hydroxylamine (NH2OH), followed by heating in the presence of an acid catalyst. The resulting compound, ZY-7, is then treated with a solution of sodium nitrite (NaNO2) and hydrochloric acid (HCl) at low temperature. Identify the class of compound that ZY-7 most likely belongs to after this series of reactions."

- A synthetic organic molecule, G, which contains both aldehyde and ether functional groups, is subjected to a series of reactions in a multi-step synthesis pathway. In the first step, G undergoes a Wittig reaction, leading to the formation of an alkene, H. Subsequently, H is treated with an ozone (O3) reagent followed by a reducing agent in an ozonolysis reaction, resulting in the formation of two different products, I and J. Considering the functional groups present in G and the nature of the reactions involved, what are the most probable structures or functional groups present in products I and J? A. I contains a carboxylic acid group, and J contains an aldehyde group. B. I contains a ketone group, and J contains an alcohol group. C. I and J both contain aldehyde groups. D. I contains an ester group, and J contains a ketone group. Don't use chat gpt.arrow_forward5. Isomeric compounds that rapidly interconvert by the movement of a proton like for example ketone formation from enol.arrow_forwarda. Propose a mechanism for the following reaction: b. Given that ΔH° for the reaction is -42 kcal/mol and the bond dissociation enthalpies for the C¬H, C¬Cl, and O¬H bonds are 101, 85, and 105 kcal/mol respectively, calculate the bond dissociation enthalpy of the O¬Cl bond.arrow_forward
