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

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion
  3. CIf assertion is true but reason is false
  4. DIf both assertion and reason are false.

Correct answer

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

Step-by-step solution

Sucrose is a non-reducing sugar as it does not reduce Tollen's or Fehling's reagent, due to absence of free aldehyde or ketone group. It contains stable acetal or ketal structure which cannot be opened into a free carbonyl group. Sugar is composed of -D-glucopyranose unit and -D-fructofuranose unit. These units are joined by - -glycosidic linkage between C -1 of the glucose unit and C-2 of the fructose unit.
