Examples showing how to go from a Newman Projection to a line bond Wedge and Hatch structure and vice versa!
A Newman projection looks at the conformations about a pair of carbon atoms. They can be any two carbon atoms you choose. In this case, they wanted to show the relation between the methyl group on C-1 and the groups on the neighbouring carbon atoms (C-2 and C-6). They simply chose to look at the C-1, C-2 bond.
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.

Replace the hydrogen atoms with the appropriate atoms.3.11 To Add a Newman Projection. To add a Newman projection, use the following tool: This tool allows to add a Newman projection. The changes become permanent only when the mouse button is released. To add a Newman projection, click on the background. Contrarily to other tools existing atoms are never used by this tool.Optical activity or stereoisomerism is a very important topic. To understand a lot of concepts of organic chemistry it is important to first understand how t...This is why the Newman projection is useful but it takes some getting used to. It is an odd point of view looking down the end of a bond, and so it is very easy to add or lose carbons. How to: In the Newman projection, we are looking down the bond between two adjacent atoms. We only draw the front atom. The second atom is obscured behind the first.As mentioned earlier, for drawing a Newman projection of a molecule, the bond, and the viewer’s angle must be given. ...

Label the configuration of each stereocenter in the resulting hydrobenzoin as either (R) or (S). If drawing a Newman projection does not look like an option you’d take, remember that there is also the swap method for determining the R and S configuration. So, when the lowest priority is neither wedge nor a dash, there is this simple yet such a useful trick making life a lot easier. And that is the swap method.
