Question

To convert glucose to saccharic acid, the reagent used is:

• A. Bromine water
• B. Fehlings solution
• C. Nitric acid
• D. Alkaline solution of Iodine

Answer 1

The correct option is C Nitric acid

To convert glucose to saccharic acid, the reagent used is nitric acid.

Dilute nitric acid oxidises glucose to saccharic acid. Primary $-OH$ group and $-CHO$ group of glucose are oxidised to $-COOH$ group.

Dilute nitric acid also oxidises gluconic acid to saccharic acid.

Primary $-OH$ group of gluconic acid is oxidised to $-COOH$ group.

Option C is correct.
