(Please write the answer neatly) Draw the Fischer projection formulas for the following isomers of D-fructose: (a) an epimer (b) an enantiomer (c) a diastereomer.
The Fischer projection is an early solution to the problem of drawing 3-dimensional molecules on a 2-dimensional page. Think of a light source illuminating a 3-dimensional object that casts a shadow on a flat surface. If these objects are always arranged in a consistent way, we can infer the 3 … See more Recall how the Fischer projection works. The longest carbon chain is arranged vertically and the substituents are drawn out to the side. … See more Recall that the Cahn-Ingold-Prelog (CIP) rules for determining R and S configurations outline a set of rules for assigning priorities … See more The next step is to assign priorities.
