Chemistry - Biomolecules Question with Solution | TestHub

Question Explanation:

On oxidation with dilute HNO₃, an aldose is converted into an aldaric acid . We need to identify which sugar gives an optically inactive (meso) aldaric acid .

Concept:

This question is based on Oxidation of aldoses, Aldaric acids, Meso compounds, Optical activity Solution:

Dilute HNO₃ oxidizes both the –CHO group and –CH₂OH group of an aldose into –COOH , forming an aldaric acid
