Identify the product formed when glucose is treated with dil. HNO ₃ .
Options
- ASaccharic acid
- BOxalic acid
- CGluconic acid
- DMalonic acid
Correct answer
A. Saccharic acid
Step-by-step solution
Glucose on oxidation with dilute nitric acid ( HNO ₃ ) yields a dicarboxylic acid known as saccharic acid. Dilute HNO ₃ is a strong oxidizing agent that oxidizes both the terminal aldehyde group ( - CHO ) and the terminal primary alcohol group ( - CH ₂ OH ) of glucose into carboxylic acid groups ( - COOH ). CHO -( CHOH )₄- CH ₂ OH dil. HNO ₃ COOH -( CHOH )₄- COOH Thus, the product formed is saccharic acid. Answer: Saccharic acid
