Bonus question 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 an optically inactive alditol. When the same D-aldopentose was subjected to Wohl degradation followed by HNO3, it produced an optically inactive aldaric acid. Provide the name of this D-aldopentose.
