WebD, all represent pairs of diastereomers because they are non-superimposable and are not mirror images. A few rules regarding Fischer projection that will be explored further in the exercises are as follows: 1. Fischer projections may be turned 180°. 2. Fischer projections may not be turned 90°. 3. WebA Fischer projection is a drawing of a 3D molecule as a flat structure. The chiral carbons are represented by crossed lines. In addition to carbohydrates, it is useful for other molecules that have two or more chiral carbons. Fischer projections are useful for differentiating between enantiomers, diastereomers, and meso compounds.
