- Grignard 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_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.
