SOLVED: Write the chemical equation for the formation of (1) furfural (2) hydroxymethylfurfural from fructose.

5 Hydroxymethylfurfural

SOLVED:Furfural, which is prepared from corncobs, is an important solvent in synthetic rubber manufacturing, and it is reduced to furfuryl alcohol, which is used to make polymer resins. Furfural can also be oxidized to 2-furoic acid. (a) Which of these compounds can form H bonds? Draw structures in each case. (b) The molecules of some substances can form an internal H bond, that is, an H bond within a molecule. This takes the form of a polygon with atoms as corners and bonds as sides and an H bo
