Question

Given below are two statements labelled as Assertion (A) and Reason (R).
Assertion (A): Glucose and fructose can be distinguished by Tollens’ reagent.
Reason (R): Glucose contains an aldehyde group while fructose contains a keto 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 D A is false but R is true

Glucose and fructose can not be distinguished by Tollens’ reagent as both respond positively with this reagent. So, the assertion is false however reason is true.
So, the correct answer is option (d).
