Assertion: maltose is reducing sugar R...

Assertion: maltose is reducing sugar
Reason : In maltose 1-2 glycosidic linkage is present so free CHO
group present which is responsible for reducing nature

A

If both assertion & Reason are ture & the Reason is a correct explanation of the Assertion

B

If both Assertion & Reason ar True but Reason is not a correct explantation of the Assertion

C

If Assertion is True but the Reason is False

D

If both Assertion & Reason are false

The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step 1: Analyze the Assertion - **Assertion**: "Maltose is a reducing sugar." - **Explanation**: Maltose is indeed a reducing sugar. Reducing sugars are those that can donate electrons or reduce another molecule. Maltose can reduce Benedict's solution, which confirms its status as a reducing sugar. ### Step 2: Analyze the Reason - **Reason**: "In maltose, 1-2 glycosidic linkage is present so free CHO group present which is responsible for reducing nature." - **Explanation**: This statement is incorrect. Maltose actually has a 1,4-glycosidic linkage, not a 1,2-glycosidic linkage. The presence of a free aldehyde group (CHO) is what contributes to the reducing nature of maltose, but the reason provided incorrectly describes the type of glycosidic linkage. ### Step 3: Conclusion - Since the assertion is true (maltose is a reducing sugar) and the reason is false (the type of glycosidic linkage is incorrectly stated), we conclude that the correct answer is that the assertion is true, but the reason is false. ### Final Answer - The correct option is: **Assertion is true but reason is false.** ---
