IIT JEE Revision Hydrolysis of Sucrose

Sucrose is hdyrolysed by concentrated alcoholic solution of hydrochloric acid.

The hydrolysis is carried out at about 323 K by heating on a water bath for about two hours.

Hydrolysis gives glucose and fructose

C12H22O11 --> C6H12O6 + C6H12O6

Glucose and fructose both have the same molecular formula.

Glucose being almost insoluble in alcohol crystallises on colling while fructose being comparatively more soluble remains in the solution
