$Br_2/H_2O$

Vedclass · Answer

(C) $Br_2/H_2O$ is a mild oxidizing agent that can oxidize an aldose (like glucose) to a carboxylic acid (gluconic acid) but cannot oxidize a ketose (like fructose).Since glucose contains an aldehyde group,it undergoes oxidation,whereas fructose,which contains a ketone group,does not react under these conditions.Therefore,$Br_2/H_2O$ is used to differentiate between glucose and fructose.
