MHT CET 2025 Chemistry question

Which carbon atoms of glucose and fructose respectively forms glycosidic linkage in sucrose?

(A)C-1 and C-2Correct
(B)C-2 and C-1
(C)C-2 and C-6
(D)C-1 and C-5

Answer: (A)

Solution

Sucrose is a non-reducing disaccharide in which -D-glucopyranose and -D-fructofuranose are joined by an -1,2-glycosidic linkage between C-1 of glucose and C-2 of fructose. Both anomeric (reducing) carbons, C-1 of
