Question

Which of the following statements is chemically accurate regarding the cyclic structure and reactivity of D-Fructose?

Answer: B

💡 Solution & Explanation

D-Fructose is a ketohexose that forms a 5-membered cyclic hemiketal (furanose). Although ketones generally don't reduce Fehling's solution, fructose does because the alkaline medium isomerizes it into glucose and mannose (Lobry de Bruyn-van Ekenstein rearrangement).
