    If same amount of sucrose \[\left( {{C}_{12}}{{H}_{22}}{{O}_{11}} \right)\] is taken instead of glucose then

    A) elevation in boiling point will be higher

    B) depression in freezing point will be higher

    C) depression in freezing point will be lower

    D) both [a] and [b].

    Correct Answer: C

    Solution :

    Depression in freezing point or elevation in boiling point is proportional to molarity which is proportional to number of moles. For same amount, higher the molar mass of solute lower will be number of moles. Hence, lower will be the colligative property.
