Which monosaccharides are formed in the Kiliani-Fischer synthesis starting with D-xylose?

Question

Quizplus · Accepted Answer

The Kiliani-Fischer synthesis involves the reaction of a aldose with hydrogen cyanide (HCN) followed by hydrolysis to produce the corresponding aldose with one additional carbon atom. Starting with D-xylose (a 5-carbon aldose), the product of this reaction will be a 6-carbon aldose. The only option among the given choices that includes a 6-carbon aldose is D-glucose (a 6-carbon aldose) and D-idose (a 6-carbon ketose). Therefore, the monosaccharides formed in the Kiliani-Fischer synthesis starting with D-xylose are D-glucose and D-idose, and the correct answer is B.
