The mechanism for the base-catalyzed conversion of D-fructose to D-glucose and D-mannose has to be written. Concept Introduction: In the conversion of D-fructose to D-glucose the base is required as a catalyst. Therefore, such reactions are called base catalyzed reactions. The base first removes a proton from carbon position 1 and forms an enolate ion. The enolate ion is further protonated by the other proton. That proton comes from the top or from the bottom of the planar sp 2 -hybridized carbon.

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.
