Question

Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R
Assertion: Glucose does not give 2,4-DNP test.
Reason: Glucose exists in cyclic hemiacetal form.
In the light of the above statements, choose the correct answer from the options given below

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (A)

If both assertion and reason are true and reason is the correct explanation of assertion

Answer 2

As the glucose exists in cyclic hemiacetal form, this indicates that the aldehydic group in glucose is not free and hence it does not give $2,4$-DNP test.
