Vedclass · Answer

(B) Glucose is an aldohexose containing an aldehyde group $(-CHO)$,whereas fructose is a ketohexose containing a ketone group $(-C=O)$.Because of the presence of the aldehyde group,glucose acts as a reducing sugar and gives a positive silver mirror test with Tollen's reagent.Fructose,although a ketose,also gives a positive test due to its isomerization into glucose and mannose in the alkaline medium of the reagent,but glucose is specifically characterized by its aldehyde functionality which is the primary structural difference.
