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.
