- An unknown hydrocarbon A with the formula C6H10 reacts with 1 molar equivalent of H2 over a palladium catalyst to give B C6H12 (Rxn 1). Hydrocarbon A also reacts with OsO4 to give the glycol C (Rxn 2). A gives 5-oxohexanal on ozonolysis (Rxn 3). Draw the structures of A, B, and C. Give the reactions.arrow_forwardWhen 1-butanol is treated with conc. H2SO4 and heat .A product 'A' is formed from the reaction. Treatment of 'A' with HCl/H2O gives 'B'. Treatment of 'A' with cold KMnO4/OH- gives 'C' Treatment of 'A' with hot KMnO4 /OH- gives 'D' followed by acidification of the mixture to give 'E' 1. identify the compounds represented by A,B,C,D and E.arrow_forwardCompound A (C7H11Br) is treated with magnesium in ether to give B (C7H11MgBr) which reacts violently with D2O to give 1-methylcyclohexene with a deuterium atom on the methyl group (C). Reaction of B with acetone (Ch3COCH3) followed by hydrolysis gives D (C10H18O). Heating D with concentrated H2SO4 gives E (C10H16), which reacts with 2 equivalents of Br2 to give F (C10H16Br4). E undergoes hydrogenation with excess H2 and Pt catalyst to give 2-methylpropylcyclohexane. Determine the structures of compounds A through F, and show your reasoning throughout.arrow_forward
