A) C-2 of $\alpha$-D-glucopyranose and C-2 of $\beta $- D fructofuranose

B) C-1 of $\alpha$-D-glucopyranose and C-2 of $\beta $- D fructofuranose

C) C-1 of $\alpha$-D-glucopyranose and C-6 of $\beta $- D fructofuranose

D) C-2 of $\alpha$-D-glucopyranose and C-3 of $\beta $- D fructofuranose ?

Answer:

Option B

Explanation:

C-1 of $\alpha$-glucopyranose and C-2 of $\beta $- D fructofuranose respectively are linkage together to form glycosidic linkage in sucrose. It is shown  below:
