Monosaccharides - Strong Oxidation (Aldaric Acid) Practice Problems

Which of the following pairs of aldohexoses produces identical aldaric acids when oxidized?

Determine the number of aldaric acids produced from the eight D-aldohexoses.

Draw the products expected from the nitric acid oxidation of the following monosaccharides.

a. D-glucose
b. D-talose

D-Allose and D-altrose are kept in two unlabeled bottles A and B. To identify them, both of these are treated with nitric acid. The component of bottle A gives an optically inactive aldaric acid, while the component of bottle B gives an optically active aldaric acid. Identify which bottle contains D-allose and which one contains D-altrose.

Determine which of the following monosaccharides will produce an optically active aldaric acid when subjected to oxidation with nitric acid.

Determine which of the given monosaccharides will produce an optically active aldaric acid when subjected to oxidation with nitric acid (HNO₃).

i. Aside from D-idose, what other aldohexose can undergo oxidation by nitric acid to produce D-idaric acid?

ii. Give another name for D-idaric acid.

What sugar, other than D-talose, produces D-talaric acid when it undergoes oxidation with nitric acid?
