Question

Sucrose is dextrorotatory but the mixture obtained after hydrolysis is laevorotatory. Explain.

Answer 1

Answer:

Sucrose is dextrorotatory. On hydrolysis, it produces a mixture of glucose and fructose having specific rotation +52.5∘ and -92.4∘. Thus, the respectively net resultant mixture become laevorotatory. Hence, the mixture is laevorotatory and product is known as invert sugar.

Answer 2
