Question
Chapter 21.5, Problem 10P
Interpretation Introduction
Interpretation:
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
