D-glucose & D-fructose can be differentiated by :

AFehling solution
BTollens reagent
CBenedict test
D$$Br_2/H_2O$$
Correct Answer

Solution

$$Br_2/H_2O$$ 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.

Therefore, the correct option is D.
