Identify the product formed when glucose is treated with dil. HNO ₃ .

Options

  1. ASaccharic acid
  2. BOxalic acid
  3. CGluconic acid
  4. 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
