Question

Given below are two statements labelled as Assertion (A) and Reason (R).
Assertion (A): Glucose and fructose are reducing sugars.

Reason (R): Glucose and fructose contain a free aldehydic and ketonic froup adjacent to a $H\underset{|}{\stackrel{|}{C}}OH$ group.

• A. Both A and R are true and R is the correct explanation of A
• B. Both A and R are true but R is not the correct explanation of A
• C. A is true but R is false
• D. A is false but R is true

Answer 1

The correct option is A Both A and R are true and R is the correct explanation of A

Reducing sugars contain a free aldehydic or ketonic group adjacent to a $H\underset{|}{\stackrel{|}{C}}OH$ group and reduce Tollen's reagent, Schiff's reagent or Benedict's solution.
Thus, both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
