of molybdic acid in aqueous solution, the 2-ketohexoses d -fructose, l -sorbose and d -tagatose undergo a stereospecific intramolecular rearrangement to give the corresponding 2- C -(hydroxymethyl)aldoses, 2- C -(hydroxymethyl)- d- ribose ( d -hamamelose), 2- C -(hydroxymethyl)- l -lyxose, and 2- C -(hydroxymethyl)- d -xylose, respectively. At equilibrium, the ratio of 2-ketose to 2- C -(hydroxymethyl)aldose
