In the Charring process, concentrated sulfuric acid reacts with sugar to give sugar charcoal. What is the role of conc. H ₂ SO ₄ in this reaction?

Options

  1. AAn oxidizing agent
  2. BA sulfonating agent
  3. CA dehydrating agent
  4. DA decomposing agent

Correct answer

C. A dehydrating agent

Step-by-step solution

The reaction of concentrated sulfuric acid with sugar (sucrose) is known as the charring process. C ₁₂ H ₂₂ O ₁₁ conc. H ₂ SO ₄ 12 C + 11 H ₂ O In this reaction, concentrated sulfuric acid removes water molecules from the sugar molecule, leaving behind a black mass of elemental carbon, which is called sugar charcoal. This demonstrates the strong affinity of concentrated sulfuric acid for water. Therefore, concentrated H ₂ SO ₄ acts as a strong dehydrating agent. Answer: A dehydrating agent
