Which of the following will reduce Tollens' reagent ? Explain.

Answer»

<P>

Solution :In DISACCHARIDE (Q), both the monosaccharides are linked through their reducing centres `(C_1)`, therefore , it is not a reducing disaccharide. In disaccharide (P), the reducing end `(C_1)` of one MONOSACCHARIDE is linked to NON -reducing end `(C_4)` of the other monosaccharide. In other wordsm, reducing end of one monosaccharide is free. Therefore, it is a reducing dissaccharide.
