Question

Assertion : Sucrose is a non-reducing sugar.
Reason : It has a glycosidic linkage.

Options:

A . If both assertion and reason are true and the reason is the correct explanation of the assertion.

B . If both assertion and reason are true but reason is not the correct explanation of the assertion.

C . If assertion is true but reason is false.

D . If the assertion and reason both are false.

E . If assertion is false but reason is true.

Answer: Option A
:
A
Option (a)
Sucrose is a non reducing-sugar as it does not reduceTollen's or Fehling's reagent, due to absence of freealdehyde or ketone groups. It contains stableacetal orketal structure which cannot be opened into a free carboxyl group.
Sucrose is composed of alpha-D-glucopyranose unit and -D-fructofuranose unit. These units are joined bya-b-glycosidic linkage betweenC-1 of the glucose unit andC- 2 of the fructose unit.
