Vedclass · Answer

(A) Fehling's reagent is used to detect the presence of reducing sugars. Reducing sugars contain a free hemiacetal or hemiketal group,which allows them to act as reducing agents. $Sucrose$ is a non-reducing sugar because it is a disaccharide formed by the linkage of $Glucose$ and $Fructose$ through their respective anomeric carbons,leaving no free hemiacetal group. Therefore,$Sucrose$ does not give a reddish-brown precipitate with Fehling's reagent. $Lactose$,$Glucose$,and $Maltose$ are all reducing sugars and will give a positive test.

Sugar which does not give reddish brown precipitate with Fehling's reagent is:
