Text Solution

Verified by Experts

The correct Answer is:
A
Sucrose is a non-reducing sugar as it does not reduce tollen's pr fehling's reagent,due to absence of free alfehyde or ketone group.It contains stable acetal or ketal structure which cannot be opened into a free carboxyl group.
Sugar is composed of `alpha`D-glucopyranose unit and`beta`-D-fructofuranose unit.These units are joined by`alpha`-`beta`-glycosidic linkage between C- of the glucose unit and C-2 of the fructose unit.
