Vedclass · Answer

(C) Aldoses contain an aldehyde group $(-CHO)$,while ketoses contain a ketone group $(>C=O)$.$Br_2$ water is a mild oxidizing agent that oxidizes the aldehyde group of an aldose to a carboxylic acid (gluconic acid) but does not oxidize ketoses.Therefore,$Br_2$ water can distinguish between aldoses and ketoses.Tollen's reagent and Fehling's solution are oxidizing agents that react with both aldoses and ketoses (due to the tautomerization of ketoses into aldoses in alkaline medium),so they cannot distinguish between them.Thus,only $I$ is the correct reagent.

Consider the following reagents:
$I$. $Br_2$ water
$II$. Tollen's reagent
$III$. Fehling's solution
Which of these can be used to distinguish between an aldose and a ketose?
