Fischer projections are msot commonly used to represent biomolecules such as amino acids and carbohydrates sugars as the provide a quick way of representing one or more multiple. Before getting to drawing its Fischer projection lets number the carbons in any order no IUPAC rules needed. We can see that the structure is actually wrapped around like a broken circle.

1021ja01045a049 Classic paper by Prof. They tend to be less commonly used by organic chemists. The Newman projections are still not perfect because the back bonds that should be obscured by the circle are still a little bit visible but its definitely better than it was.

Staple the hardcopies to this sheet and turn the packet in at the beginning of. Drawing the Newman Projection from a 3-dimensional molecule in which not all of the atoms are shown. Grab a pen and some paper and use the model to draw Newman projections for each of these from the point of view indicated by the beady little eye.

The optimal solution would be for the circle to be able to obscure atoms and bonds behind it and to reveal atom and bonds in front of it just like happens in MarvinJS.
