Question

Predict-the-Product. Draw the structure(s) of the major organic product(s) formed in the following reactions. Please indicate stereochemistry where appropriate. 

**Title: Sulfuric Acid Catalyzed Reaction of Glucose with Acetone** **Introduction:** An important chemical reaction involves the acid-catalyzed reaction of monosaccharides, such as glucose, with acetone. This reaction is often used in organic chemistry and biochemistry. Here, we will illustrate and explain this synthesis process. **Reaction Scheme:** The schematic represents glucose reacting with acetone in the presence of sulfuric acid (H₂SO₄) as a catalyst. The reactants and the product of the reaction are shown below. **Reactants:** 1. Glucose: A hexose sugar with six carbon atoms arranged in a ring structure. Its molecular formula is C₆H₁₂O₆. 2. Acetone: A simple ketone with the molecular formula C₃H₆O. 3. Sulfuric Acid (H₂SO₄): A strong acid used as a catalyst. ### Reaction Summary: \[ \text{Glucose} + \text{Acetone} \xrightarrow{\text{H}_{2}\text{SO}_{4}} \text{Product} \] **Detailed Reaction Mechanism:** 1. **Glucose Structure**: The glucose molecule is shown in its cyclic form, with hydroxyl (OH) groups attached to several carbon atoms around the ring. - Each corner of the hexagonal ring represents a carbon atom. - The oxygen atom in the ring is part of the glucose's cyclic ether functionality. 2. **Reaction with Acetone**: - Acetone (C₃H₆O) is shown here with a central carbonyl group (C=O). - Under acidic conditions (H₂SO₄), acetone can participate in ketal or acetal formation reactions with glucose. The product of this reaction often involves protection of the glucose molecule's hydroxyl groups through the formation of ketals or acetals, which are more resistant to further reactions. **Graph and Diagram Explanation:** - The left part of the diagram illustrates the structure of glucose with its hydroxyl groups. - An arrow points to the right, representing the direction of the reaction. - Above the arrow, "H₂SO₄" is written, indicating that sulfuric acid acts as the catalyst. - Acetone is depicted below the arrow, with its distinctive carbonyl group (C=O). - The
