Statement 1: A solution of sucrose in water is dextrorotatory but on hydrolysis in presence of little hydrochloride acid, it becomes laevorotatory.
Statement 2: Sucrose on hydrolysis gives unequal amounts of glucose and fructose as a result of which change in sign of rotation is observed.

A

Statement 1 is True, Statement 2 is True, Statement 2 is Correct explanation for Statement 1.

B

Statement 1 is True, Statement 2 is True, Statement 2 is NOT a correct explanation for Statement 1.

C

Statement 1 is True, Statement 2 is False.

D

Statement 1 is False, Statement 2 is True.

Text Solution

Verified by Experts

The correct Answer is:
C
Sucrose on hydrolysis gives equal amounts of glucose and fructose. Since glucose has less positive and fructose has more negative magnitude of rotation, therefore, change in sign of rotation is observed.
