Question

Rapid interconversion of $\alpha$ - D - glucose and $\beta$- D- glucose in solution is known as:

• A. racemization
• B. asymmetric induction
• C. fluxional isomerization
• D. mutarotation

Answer 1

Answer: (D)

mutarotation

The change in the optical rotation due to change in equilibrium of two anomers when the corresponding stereocentres inconvert is known as mutarotation. Rapid interconversion of $$\alpha$-D-glucoseand$\beta $ -D - glucose in solution is therefore known as mutarotation.
