MCQ
Glucose and Fructose can be differentiated by
- ATollens's reagent
- BCold $KMnO_4$
- ✓$Br_2/H_2O$
- 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.
