Question:

Assertion: Fructose reduces Fehling's solution and Tollen's reagent.

Reason: Fructose does not contain any aldehydic group. 

Options:

Both Assertion and Reason are correct and the Reason is the correct explanation for the Assertion.

Both Assertion and Reason are correct and the Reason is not the correct explanation for the Assertion.

Assertion is correct but the Reason is incorrect.

Assertion is incorrect but the Reason is correct.

Correct Answer:

Both Assertion and Reason are correct and the Reason is not the correct explanation for the Assertion.

Explanation:

Fructose contains the α-ketol group, i.e., -COCH2OH which gets converted into the α-aldol group, i.e., -CHOHCHO group under basic conditions of the reaction and hence reduces Fehling's solution and Tollen's reagent.
