Vedclass · Answer

(A) Glucose is an aldose containing an aldehyde group,while fructose is a ketose containing a ketone group.$I$. Bromine water ($Br_2$ water) is a mild oxidizing agent that oxidizes the aldehyde group of glucose to gluconic acid,but it does not oxidize fructose. Thus,it can distinguish between them.$II$. Tollen's reagent $(Ag(NH_3)_2^+)$ oxidizes both aldoses and ketoses (due to tautomerization of fructose into glucose in basic medium). Therefore,it cannot distinguish between them.$III$. Schiff's reagent reacts with free aldehyde groups. While glucose has an aldehyde group,fructose does not. However,in the presence of Schiff's reagent,fructose does not show a positive test,but glucose does. Thus,it can also distinguish between them.Therefore,both $I$ and $III$ can be used to distinguish glucose and fructose.
