None 3. a.(i)(ii)An aldopentose H is reduced by sodium borohydride (NaBH4) to produce anoptically inactive alditol, I. Elongation of H, via Kiliani-Fischer synthesis,produces J, which undergoes oxidation by nitric acid to an optically inactivediacid, K. Aldopentose H has the L configuration.Draw the open chain Fischer projections of compounds H, I, J & K and explainyour answer.Discuss the mechanism for the first step (the step using NaCN) of the Kiliani-Fischer elongation.
