- An unknown hydrocarbon Q has a formula C6H12. Q reacts with osmium tetroxide to give a diol R when oxidized with KMnQ4 in an acidic medium Q gives two products. One product is propanoic acid and the other is ketone S. Provide reaction equations to identify the possible structures of Q, R and S.arrow_forwardAn 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_forwardOn being heated with a solution of sodium ethoxide in ethanol, compound A (C7H15Br) yielded a mixture of two alkenes B and C, each having the molecular formula C7H14. Catalytic hydrogenation of the major isomer B or the minor isomer C gave only 3-ethylpentane. Suggest structures for compounds A, B, and C consistent with these observations.arrow_forward

Which of these aldehydes are chiralarrow_forwardCompound AA has a molecular formula of C3H6O and gives a positiveresult using Tollen’s reagent. The reaction of compound AA with hotacidified potassium permanganate, KMnO4 gives compound BB. Thecatalytic hydrogenation of compound AA with nickel, Ni producedcompound CC. The reaction of compound BB with ethanamine,CH3CH2NH2 produces compound DD I) Draw the structural formula of compounds AA, BB, CC and DD. 2)Name the type of chemical reaction for the formation of compound CC.arrow_forward
- Isoprene 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_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_forwardA compound X of molecular formula C7H14 when hydrogenated produces 2,4-dimethylpentane and when hydroborated the obtained alcohol is 2,4-dimethyl-1-pentanol. a. What is the structure of X? b. If X is reacted with H2O catalyzed by H2SO4, what product is obtained? Write the structure, give the name, and write the complete mechanism, step by step of this reaction, in such a way as to explain the formation of the compound (DO NOT FORGET THE CORRECT USE OF ARROWS!).arrow_forward
- Write structural formulas for all ketones with the molecular formula C6H12O and give each its IUPAC name. Which of these ketones are chiral?arrow_forwardHydrocarbon 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_forwardA 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_forward
