Vedclass · Answer

(A) non-reducing sugar is a carbohydrate that does not have a free aldehyde or ketone group,meaning it cannot reduce Tollens' reagent or Fehling's solution.Sucrose is a disaccharide composed of glucose and fructose linked by a glycosidic bond between their anomeric carbons ($C_1$ of glucose and $C_2$ of fructose).Since both anomeric carbons are involved in the glycosidic linkage,there is no free functional group available to act as a reducing agent.Therefore,sucrose is a non-reducing sugar.
