Given below are two statements: Statement I : Sucrose is dextrorotatory. However sucrose upon hydrolysis gives a solution having mixture of products. This solution shows laevorotation. Statement II : Hydrolysis of sucrose gives glucose and fructose. Since the laevorotation of glucose is more than the dextrorotation of fructose the resulting solution becomes laevorotatory. In the light of the above statements, choose the correct answer from the options given below.

1. Statement I is false but Statement II is true.
2. Both Statement I and Statement II are false.
3. Both Statement I and Statement II are true.
4. Statement I is true but Statement II is false.

Correct answer: Statement I is true but Statement II is false.

Solution

Statement I is accurate as sucrose is indeed dextrorotatory, and its hydrolysis results in a mixture that exhibits laevorotation. However, Statement II is incorrect because the laevorotation of the resulting mixture depends on the specific concentrations of glucose and fructose, and it is not guaranteed that glucose's laevorotation will always dominate.
