The correct Answer is:
To solve the question, we need to analyze the assertion and the reason provided. ### Step 1: Understand the Assertion (A) The assertion states that "The aqueous solutions of glucose and alcohol show acidic character." - **Analysis**: Acids are substances that can donate protons (H⁺ ions) in solution. Glucose (C₆H₁₂O₆) and alcohol (commonly ethanol, C₂H₅OH) do not dissociate into ions that can donate H⁺ ions when dissolved in water. Therefore, they do not exhibit acidic behavior. ### Step 2: Understand the Reason (R) The reason states that "Aqueous solutions of glucose and alcohol give OH⁻ ions." - **Analysis**: Glucose and alcohol do not dissociate to produce OH⁻ ions either. They remain as intact molecules in solution. While water does contain OH⁻ ions, these are not produced by glucose or alcohol; they are inherent to the water itself. Thus, the statement is misleading. ### Step 3: Conclusion - Since the assertion is false (A is false) and the reason is also misleading (R is false), we conclude that neither the assertion nor the reason is correct. ### Final Answer Both A and R are false. ---
