An optically active D-aldohexose was treated with NaBH/H2O and
produced an optically inactive alditol. When the same D-aldohexose
was subjected to Wohl degradation followed by HNO3 it produced an
optically inactive aldaric acid. What is the structure of this D-
aldohexose?
O D-glucose
O D-mannose
O D-allose
O D-idose
