MCQ
Glucose and Fructose can be differentiated by
  • A
    Tollens's reagent
  • B
    Cold $KMnO_4$
  • $Br_2/H_2O$
  • D
    $PCC$

Answer

Correct option: C.
$Br_2/H_2O$
c
$Br _2 / H _2 O$ being a mild oxidising agent can only oxidise aldose to carboxylic acids but cannot oxidise ketose.As glucose contains aldehyde group it gets oxidised and converted into a carboxylic acid and is differentiate from fructose which has ketone group.

The boiling point of water in a $0.1$ molal silver nitrate solution (solution $A$ ) is $x ^{\circ} C$. To this solution A, an equal volume of $0.1$ molal aqueous barium chloride solution is added to make a new solution $B$. The difference in the boiling points of water in the two solutions $A$ and $B$ is $y \times 10^{-2}{ }^{\circ} C$.

(Assume : Densities of the solutions $A$ and $B$ are the same as that of water and the soluble salts dissociate completely.)
