How to draw newman projections from wedge dash.

The first things to note when drawing Fischer projections are the general rules for drawing them. The first general rule concerns the choices of 'top' and 'bottom' while the second concerns how each cross is interpreted. In a Fischer projection, the carbon atom with the highest oxidation state should be closer to the top than the bottom.

How to draw newman projections from wedge dash. Things To Know About How to draw newman projections from wedge dash.

A Fischer projection may not be rotated by 90 degrees. Such a rotation typically changes the configuration to the enantiomer. To find the enantiomer of a molecule drawn as a Fischer projection, simply exchange the right and left horizontal bonds. To determine whether the molecule in Fischer projection is a meso compound, draw a horizontal line ...In order to draw a Newman projection from a wedge-dash diagram, it is useful to imagine putting your "eye" in line with the central bond in order to look along it.
