  • Assertion : A solution of surcose of sucrose in water is dextrorotatory. But on hydrolysis in the presence of little hydrochloric acid, it becomes levorotatory. Reason : Sucrose hydrolysis gives unequal amounts of glucose and fructose . As a result of this change in sign of rotation is observed .
