The correct Answer is:
To analyze the statements regarding fructose, we need to evaluate each statement carefully. **Step 1: Evaluate Statement 1** - Statement 1 claims that "Fructose reduces Fehling's solution and Tollen's reagent." - Fructose is a ketose sugar, specifically an alpha-hydroxy ketone. Although it does not contain an aldehyde group, it can still reduce these reagents due to its structure. - In the presence of Fehling's solution (which contains copper ions) and Tollen's reagent (which contains silver ions), fructose can undergo tautomerization to form an aldehyde, which is capable of reducing these reagents. - Therefore, Statement 1 is **true**. **Step 2: Evaluate Statement 2** - Statement 2 states that "Fructose does not contain any aldehyde group." - Fructose is indeed a ketose and does not have an aldehyde group in its structure. It has a ketone functional group instead. - Therefore, Statement 2 is also **true**. **Step 3: Conclusion** - Since Statement 1 is true (fructose can reduce Fehling's and Tollen's reagents by forming an aldehyde) and Statement 2 is true (fructose does not contain an aldehyde group), we conclude: - Statement 1 is true. - Statement 2 is true, but it does not explain the reducing property of fructose. Thus, the correct interpretation of the statements is that Statement 1 is true, and Statement 2 is true but does not provide a valid reason for the first statement. ### Final Answer: - Statement 1: True - Statement 2: True (but does not explain the reducing property)
