AIIMS 2019 Chemistry Disaccharides MCQ Question
Assertion: Two sugar units joined by 1,2-glycosidic bond in sucralose.
Reason: It contains 1 C-glucose and 2 C -fructose glycosidic bond
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Correct Answer
Detailed Explanation
Sucralose is derived from sucrose through the chlorination of specific hydroxyl groups, resulting in a compound that retains the sweetness of sugar while being non-caloric. The statement regarding the glycosidic bond is incorrect; sucralose does not contain a C₁–glucose and C₂–fructose glycosidic bond, as it is not a disaccharide but rather a modified monosaccharide. Therefore, option A is correct in identifying that the description of the glycosidic bond is inaccurate. Other options are not applicable as they do not provide relevant information to the question.
