    Direction for: In each of the following questions a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statements mark the correct answer as

    Assertion: Maltose is a reducing sugar which gives two moles of D-glucose on hydrolysis. Reason: Maltose has a 1, 4-\[\beta \]-glycosidic linkage.                                           

    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.

    Correct Answer: C

    Solution :

    Maltose, a disaccharide\[({{C}_{12}}{{H}_{22}}{{O}_{11}})\] is a reducing sugar, which upon hydrolysis yield 2 moles of \[D-(+)\]glucose. In it the two D-glucose unit are linked through \[\alpha \]-glycosidic linkage between \[C-1\] of one glucose unit and \[C-4\]of the other.
