Assertion: Two sugar units are joined by 1,2-glycosidic bond in sucralose. Reason : Sucralose contains $C_1$-glucose and $\mathrm{C}_2$-fructose glycosidic bond.

  • Correct answer
    A
    If both assertion and reason are true and reason is the correct explanation of assertion.
  • B
    If both assertion and reason are true but reason is not the correct explanation of assertion.
  • C
    If assertion is true but reason is false.
  • D
    If both assertion and reason are false.

Solution

Sucralose is an artificial sweetener which is trichlorosucrose, $\mathrm{C}_{12} \mathrm{H}_{19} \mathrm{Cl}_3 \mathrm{O}_8$. Thus, its structure is same as that of sucrose.

Hence, the correct answer is option: 'A'.
