Question

Quizplus · Accepted Answer

Monosaccharides have the ability to exist in both open-chain and closed-ring forms, but in solution, they prefer the closed-ring form as it is more stable. In this form, the carbonyl group of the monosaccharide reacts with a hydroxyl group on a different carbon atom to form a hemiacetal ring. Therefore, option B is the best choice as it correctly states that a monosaccharide prefers to exist in the closed-ring form.
