Question

Quizplus · Accepted Answer

α-D-Xylofuranose has five hydroxyl groups that can react with methyl iodide in the presence of a silver salt catalyst (Ag2O). Each hydroxyl group can be methylated, leading to the reaction of five equivalents of methyl iodide with each equivalent of the furanose.
