- 3. The reaction of bromine with 3-hexanone produces two isomeric products of formula C6H11BrO. Give the mechanism for obtaining the two isomers.arrow_forward3b)Give the mechanisms for the following transformations:arrow_forwardIsoprene has sometimes been used as a starting material in the laboratory synthesis of terpenes. In one such synthesis, the first step is the electrophilic addition of 2 mol of hydrogen bromide to isoprene to give 1,3-dibromo-3-methylbutane.Write a series of equations describing the mechanism of this reaction.arrow_forward
- 5. Compound A, C 10H 18O, undergoes reaction with dilute H 2SO 4 at 50 °C to yield a mixture of two alkenes, C 10H 16. The major alkene B, gives only cyclopentanone after ozone treatment followed by reduction with zinc in acetic acid. Which of the following reactions are correct.arrow_forwardCompound A reacts with the reagents shown in the image. Write the mechanism, step by step, for the formation of product B. Note that B has the molecular formula C14 H18 O.arrow_forwardOn treatment with Cl2/hν, a compound with the formula C9H12 yields only a single monochloride. What is a possible structure of the compound?arrow_forward
- 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_forwardAlkyl halides can be reduced to alkanes by a radical reaction with tributyltin hydride, (C4H9)3SnH, in the presence of light (hv). Propose a radical chain mechanism by which the reaction might occur. The initiation step is the light-induced homolytic cleavage of the Sn-H bond to yield a tributyltin radical.arrow_forwardDiazomethane, CH2N2, is used in the organic chemistry laboratory despite its danger because it produces very high yields and is selective for reaction with carboxylic acids. Write the products of the following reactions.arrow_forward
- An unknown hydrocarbon A with the formula C6H12 reacts with 1 molar equivalent of H2 over a palladium catalyst to give hydrocarbon B. Hydrocarbon A also reacts with OsO4 to give the glycol C. When oxidized with KMnO4 in acidic solution, A gives two fragments. One fragment is propanoic acid, CH3CH2COOH, and the other fragment is ketone D (R2C=O). What are the structures of A, B, C and D? Write all reactions.arrow_forwardDraw the structure of each product from the reaction of benzene with 2-chloro-1-methylcyclohexane using AlCl 3 as the catalyst and Identify the major product.arrow_forwardCompound A, C5H11Br, on treatment with alcoholic KOH, gives two isomeric compoundsarrow_forward
