4 Both Statement I and Statement II are correct
Explanation:
(a) Both statements I and II are incorrect. The correct statements are-
Sucrose is dextrorotatory but after hydrolysis gives dextrorotatory glucose and laevorotatory fructose.
The laevorotation of fructose $\left( -{{92.4}^{\circ }} \right)$ is more than dextrorotation of glucose $\left( +{{52.5}^{\circ }} \right)$.
