    Assertion: Fructose reduces Fehling solution & Tollen's reagent.
    Reason: Fructose does not contain any aldehydic group.

    A) Assertion and reason both are correct statements and reason explains the assertion.         

    B) Assertion and reason both are correct statements but reason does not explain assertion.  

    C) Assertion is correct statement and reason is wrong statement. 

    D) Assertion is wrong statement and reason is correct statement.

    Correct Answer: B

    Solution :

    Correct explanation. Fructose contains an a-ketol group \[\left( -COC{{H}_{2}}OH \right)\] which gets converted into a-hydroxy group (-CHOHCHO) under basic conditions and as a result reduces Fehling's solution and Tollen's reagent.
