1.	Give scientific reasons :In the preparation of glucose from sucrose, ethyl alcohol is added at the time of cooling.
Answer» Hydrolysis of sucrose with dilute hydrahloric acid gives glucose along with fructose. Ethyl alcohol is added at the time of cooling in the preparation of glucose, to separate glucose from fructose. Glucose being insoluble in alcohol, crystallizes out first, while fructose being more soluble in alcohol, remains in the solution.
