Compound A (C7 H11Br) is treated with magnesium in ether to give B (C7H11MgBr) which reacts violently withD2O to give 1-methylcyclohexene with a deuterium atom on the methyl group (C). Reaction of B with acetone (CH3COCH3) followed by hydrolysis gives D(C10 H18 O) Heating D with concentrated gives E(C10H16) which decolorizes vtwo equivalents of Br2 to give F (C10H16 Br4) Eundergoes hydrogenation with excess and a H2 Pt catalyst to give is obutylcyclohexane. Determine the structures of compounds A through F, and show your reasoning throughout.
