Question

Which of the following is false regarding the reaction of sucrose to give fructose and glucose?

(a) It can take place in the presence of enzyme sucrase

(b) It results in the formation of a glycosidic bond.

(c) It is an inversion reaction

(d) It is a hydrolysis reaction

Answer 1

The correct choice is (b) It results in the formation of a glycosidic bond.

The best explanation: Hydrolysis of sucrose (in the presence of either dilute acid, invertase or sucrase) results in the cleavage of glycosidic bond to give glucose and fructose. Sucrase results in the cleavage of O-C(glucose) bond, whereas invertase results in the cleavage of O-C(fructose bond).
