Sugar J is nonreducing. Upon treatment with NaOH and dimethyl sulfate followed by acid workup and nitric acid produces meso-2,3-dimethoxysuccinic acid and 2-methoxymalonic acid. When treated with acid a hexose, sugar K, and methanol are formed. When treated with nitric acid sugar K forms an optically active diacid. When subjected to Ruff degradation sugar K forms a pentose, sugar M . When treated with nitric acid sugar M forms an optically active diacid, N. Show the structures all compound J-N. Explain your reasoning. If there is a structure of which you are unable to determine the exact configuration, explain why it is impossible to determine from the information given.
