Question:
Identify the product formed when glucose is oxidized with concentrated nitric acid
Identify the product formed when glucose is oxidized with concentrated nitric acid
Show Hint
Concentrated nitric acid oxidises both the CHO and the terminal CH2OH of glucose to COOH.
Updated On: Nov 12, 2026
- Gluconic acid
- Saccharic acid
- Sorbitol
- Mannitol
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept
Concentrated nitric acid is a strong oxidising agent that attacks both ends of the glucose chain.
Step 2: Reaction
The CHO group at C-1 and the \(\text{CH}_{2}\text{OH}\) group at C-6 both turn into COOH.
Step 3: Product
The dicarboxylic acid formed is saccharic acid (glucaric acid). Mild oxidation with bromine water gives only gluconic acid.
Final Answer:
The product is saccharic acid. \[ \boxed{\text{(B) }\text{Saccharic acid}} \]
