The correct Answer is:
To analyze the statements provided, we can break down the reasoning step by step. ### Step-by-Step Solution: 1. **Understanding the Statements**: - **Statement 1**: Glucose and fructose can be differentiated by Fehling's solution. - **Statement 2**: Glucose is an aldose while fructose is a ketose (having a keto functional group). 2. **Analyzing Statement 1**: - Fehling's solution is a chemical test used to differentiate between reducing and non-reducing sugars. - Glucose (an aldose) is a reducing sugar and will give a positive result with Fehling's solution. - Fructose (a ketose) is also capable of giving a positive result with Fehling's solution, but it requires a specific condition: in the presence of a base, fructose can rearrange to form an aldehyde (glucose), which can then react with Fehling's solution. 3. **Conclusion for Statement 1**: - Since both glucose and fructose can give a positive result with Fehling's solution, they cannot be differentiated by this test alone. Therefore, **Statement 1 is false**. 4. **Analyzing Statement 2**: - Glucose is indeed an aldose because it contains an aldehyde group (-CHO). - Fructose is classified as a ketose because it contains a ketone group (C=O) in its structure. 5. **Conclusion for Statement 2**: - The classification of glucose as an aldose and fructose as a ketose is correct. Therefore, **Statement 2 is true**. 6. **Final Conclusion**: - Since Statement 1 is false and Statement 2 is true, the overall conclusion is that the correct answer is that Statement 1 is false and Statement 2 is true. ### Final Answer: - **Statement 1**: False - **Statement 2**: True
