Sucrose in water is dextrorotatory, `[alpha]_(D)=+66.4^(@)` when boiled with dil. HCl, the solution becomes leavorotatory , `[alpha]_(D)=-39.9^(@)`,. In this process the sucrose breaks into

Assertion: A solution of Sucrose in water is dextrorotatory but on hydrolysis in presence of little hydrochloric acid it becomes laevorotatory. Reason : Sucrose on hydrolysis gives unequal amounts of glucose and fructose as a result of which change in sign of rotation is observed.
