- 4. Compound A has the formula C 8H 8. It reacts rapidly with KMnO 4 to give CO 2 and a carboxylic acid, B (C 7H 6O 2), but reacts with only 1 molar equivalent of H 2 on catalytic hydrogenation over a palladium catalyst. On hydrogenation under conditions that reduce aromatic rings, 4, equivalents of H 2 are taken up and hydrocarbon C (C 8H 16) is produced. What are the structures of A, B, and C.arrow_forwardCompound 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.

- Hydrocarbon X has the formula C6H12.X reacts with one molar equivalent of hydrogen in the presence of a palladium catalyst to form a product having 12 primary hydrogens.Treatment of X with ozone followed by zinc in aqueous acid gives a mixture two aldehydes.What is the structure of X?arrow_forwardFollowing is a retrosynthetic analysis for the synthesis of the herbicide (S)-Metolachlor from 2-ethyl-6-methylaniline, chloroacetic acid, acetone, and methanol. Show reagents and experimental conditions for the synthesis of Metolachlor from these four organic starting materials. Your synthesis will most likely give a racemic mixture. The chiral catalyst used by Novartis for reduction in Step 2 gives 80% enantiomeric excess of the S enantiomer.arrow_forwardAmines are converted into alkenes by a two-step process called Hofmann elimination. SN2 reaction of the amine with an excess of CH3I in the first step yields an intermediate that undergoes E2 reaction when treated with silver oxide as base. Pentylamine, for example, yields 1-pentene. Propose a structure for the intermediate, and explain why it readily undergoes elimination.arrow_forward
- When 2-pentene is treated with Cl2 in methanol, three products are formed. Account for the formation of each product (you need not explain their relative percentages).arrow_forwardNitromethane is reacted with ethyl prop-2-enoate with EtO-Na+, EtOH 3 equivalents to give the product X(C16). X then reacts with H2/Raney Ni to give the product Y(C14), which in turn reacts with Na to give Z (C12). Indicate which products X, Y and Z are.arrow_forwardCompound A of molecular formula C8H14 is reduced by sodium in liquid ammonia to give compound B of molecular formula C8H16. product (Y).Both A and B undergo hydrogenation in the presence of a platinum catalyst to give 2,5-dimethylhexane. Ozonolysis of B with an oxidative workup produces a carboxylic acid of molecular formula C4H8O2. Reaction of B with a peroxyacid gives a chiral C8H14O product, but reaction with bromine gives an achiral C8H14Br2 product. What are the identities of A and B?arrow_forward
- Compound H with molecular formula C6H12O showed no reaction in chromic acid test. Compound H undergo dehydration reaction to produce compound I. Compound J is produced when compound I react with HBr. Reaction of compound J with methanol produced compound K and I. Draw the structure of H, I, J, and K.arrow_forwardCompound A (C11H23Br) is a secondary alkyl halide. On being heated with a solution of sodium ethoxide in ethanol, compound A yielded a mixture of two alkenes B and C, each having molecular formula C11H22. Catalytic hydrogenation of the major isomer B or the minor isomer C gave only 3,5-diethylheptane. Draw structures for compounds A, B, and C consistent with these observations.arrow_forwardGrignard reagent is a versatile tool in synthetic organic chemistry. Using bromocyclopentane as a starting material, show how a Grignard reagent, X, is synthesized. Reaction of X with water produces compound Y while treatment in carbon dioxide followed by hydrolysis forms compound Z. 3-methyl-2butanone reacts with X and hydrolyses to yield compound AA. Draw the structural formulae of compounds Y, Z and AA and write the chemical equations respectively.arrow_forward
