Question

Acid hydrolysis of sucrose is accompanied by a change in optical rotation.

• A. True
• B. False

Answer 1

The correct option is A True

The given statement is True.
Acid hydrolysis of sucrose is accompanied by a change in optical rotation.
Sucrose is dextrorotatory and the solution obtained after acid hydrolysis is laevorotatory. Sucrose on acid hydrolysis gives equimolar mixture of dextrorotatory glucose (+52.20 degree) and laevorotatory fructose (-92.4 degree). The laevorotation of fructose is more than the dextrorotation of glucose.
