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
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.
