What are the hydrolysis products of `(i)` sucrose and `(ii)` lactose?

Text Solution

Verified by Experts

Both sucrose and lactose are disaccharides. Sucrose on hydrolysis gives one molecule each of glucose and fructose but lactose on hydrolysis gives one molecule each of glucose and galactose.
`underset("Sucrose")(C_(12) H_(22) O_(11)) + H_(2)O overset(H_(3) O^(+)) rarr underset(D - (+) - "Glucose")(C_(6) H_(12) O_(6)) + underset(D - (-) -"Fructose")(C_(6) H_(12) O_(6))`
`underset("Lactose")(C_(12) H_(22) O_(11)) + H_(2) O overset(H_(3)O^(+))rarr underset(D - (+) - "Glucose")(C_(6) H_(12)O_(6)) + underset(D - (+) - "Galactose")(C_(6) H_(12) O_(6))`
