Question

Given below are two statements, one is labelled as Assertion (A) and other as Reason (R) :

Assertion (A): Invert sugar is more sweeter than sucrose.
Reason (R) : Invert sugar is obtained by the hydrolysis of sucrose.

Select the correct answer from the codes given below.
Codes :

  1. Both (A) and (R) are true and (R) is the correct explanation of (A)
  2. Both (A) and (R) are true but (R) is not the correct explanation of (A)
  3. (A) is true but (R) is false
  4. (A) is false but (R) is true

Answer:

Option B: Both (A) and (R) are true but (R) is not the correct explanation of (A)

Detailed Solution:

The correct answer is “Both (A) and (R) are true but (R) is not the correct explanation of (A)”.

Invert sugar is sweeter than sucrose. This is primarily due to the fact that invert sugar is a mixture of glucose and fructose, both of which are sweeter than sucrose.

Invert sugar is obtained by the hydrolysis of sucrose, but it's not the main reason for the increased sweetness. The increased sweetness is primarily due to the composition of invert sugar, which includes fructose, a particularly sweet sugar.
