despite the absence of -cho group sucrose reduces tollen's reagent

Asked by shreesh Kulkarni | 13th Feb, 2014, 07:34: PM

Expert Answer:

Sucrose is an oligosaccharide.
An oligosaccharide has both a reducing and a non-reducing end. The reducing end of an oligosaccharide is the monosaccharide residue with hemiacetal functionality, thereby capable of reducing the Tollens’ reagent, while the non-reducing end is the monosaccharide residue in acetal form, thus incapable of reducing the Tollens’ reagent.
