Sucrose is a non-reducing sugar because it lacks a free anomeric carbon, so it does not react with Tollens’ reagent.
Ref: NCERT Class 12 Chemistry > Chapter 14: Biomolecules > Topic: Carbohydrates - Disaccharides and Glycosidic Linkage
A non-reducing sugar has no free aldehyde or ketone group. Sucrose has its reducing groups involved in a glycosidic bond between glucose and fructose, making it non-reducing.
