Essay

When an optically active D-aldopentose was subjected to Kiliani-Fischer synthesis,followed by NaBH₄/H₂O,it produced a mixture of an optically active and inactive alditols.When the same D-aldopentose was subjected to Wohl degradation followed by HNO₃ it produced an optically inactive aldaric acid.Provide the structure of this D-aldopentose.
