Question

D- Glucose shows mutarotation because:

• A. it is dextrarotatory
• B. it undergoes inter conversion between its pyranose structure and furanose structure.
• C. it undergoes interconversion between its $\alpha$ and $\beta$ (+) Glucopyranose structures
• D. it undergoes interconversion with D(-) fructose.

Answer 1

Answer: (C)

it undergoes interconversion between its $\alpha$ and $\beta$ (+) Glucopyranose structures

D- Glucose shows mutarotation because it undergoes interconversion between its $\alpha$ and $\beta$ (+) Glucopyranose structures. Mutarotation is the change in optical rotation in equilibrium between two anomers, when the corresponding stereocentres interconvert.
