The correct Answer is:
To solve the question regarding the reaction of sucrose (C₁₂H₂₂O₁₁) with concentrated sulfuric acid (H₂SO₄), we can break down the process step by step: ### Step 1: Identify the Reactants The reactant in the reaction is sucrose, which has the chemical formula C₁₂H₂₂O₁₁. The other reactant is concentrated sulfuric acid (H₂SO₄). **Hint:** Look for the chemical formulas of the reactants to understand what you are starting with. ### Step 2: Understand the Role of Concentrated Sulfuric Acid Concentrated sulfuric acid acts as a dehydrating agent in this reaction. This means it removes water (H₂O) from the sucrose. **Hint:** Remember that a dehydrating agent removes water from substances, which can lead to the formation of different products. ### Step 3: Write the Reaction The reaction can be summarized as follows: \[ \text{C}_{12}\text{H}_{22}\text{O}_{11} + \text{H}_2\text{SO}_4 \rightarrow 12\text{C} + 11\text{H}_2\text{O} \] In this reaction, sucrose is broken down into carbon (C) and water (H₂O). **Hint:** Pay attention to the products formed in the reaction. What happens to the elements in the reactants? ### Step 4: Identify the Products From the reaction, we can see that the products are: - 12 moles of carbon (C) - 11 moles of water (H₂O) However, the carbon produced in this reaction is often referred to as "sugar charcoal" because it is a form of carbon that is produced from the decomposition of sugar (sucrose). **Hint:** Consider the physical state and form of the products. What does the term "sugar charcoal" imply about the carbon produced? ### Conclusion The main product obtained from the reaction of sucrose with concentrated sulfuric acid is sugar charcoal (carbon). **Final Answer:** The product obtained in the reaction is sugar charcoal (carbon).
