Final answer:
The end product of the given dehydration synthesis reaction combining four glucose molecules is C₂₄H₄₂O₂₁ plus three molecules of water (H₂O), making option (c) the correct answer.
Step-by-step explanation:
The end products of the given dehydration synthesis reaction are determined by combining four molecules of glucose (C₆H₁₂O₆). In a dehydration synthesis, also known as a condensation reaction, each bond formation between monomers releases a molecule of water (H₂O). Since four glucose molecules are combining, there would be three water molecules formed (because each bond formation releases one water molecule).
Each glucose molecule loses a hydrogen (H) and a hydroxyl group (OH) during the process to form the water molecule. Therefore, the molecular formula of the resulting product would be C₂₄H₄₄O₂₁ and the balanced reaction is C₆H₁₂O₆ + C₆H₁₂O₆ + C₆H₁₂O₆ + C₆H₁₂O₆ → C₂₄H₄₂O₂₁ + 3H₂O, which corresponds to answer choice (c).
