Answer»

Solution :(i)When sucrose is boiledwith di`H_(2)SO_(4)`in alcoholicsolution, HYDROLYSIS take place andglucoseand FRUCTOSE are formed.
` underset("Sucrose")(C_(12)H_(22)O_(11)) + H_(2)O overset(H+) tounderset("Glucose")(C_(6)H_(12)O_(6)) + underset("Fructose")(C_(6)H_(12)O_(6))`
(ii) Glucoseis PRODUCED commericallyby thehydrolysisof starchwithdiluteHClat hightemperature and pressure .
`underset("Strach")((C_(6)H_(10)O_(5)))_(n)+ nH_(2)O underset("2-3atm pr")underset("393K") overset(H^(+))tounderset("Glucose")(nC_(6)H_(12)O_(6))`
