Let's work through an example, consider drawing a Newman projection by looking at the following wedge-dash diagram of propane from the left hand side.Because that puts the hydrogen as a dash, so R/S is easy to assign. With two wedges, the structure is (2R, 3R). So the 2R position is fine, and we just switch the wedge at C-3 to a dash, and the structure is correct (2R,3S). To draw the Fischer projection, we do something similar- arbitaritly draw a structure, check R/S, and then adjust as ...There's a tap for that. Amazon’s announcement for its new vision of shopping, the Dash Button, was so bizarre, that people thought it was an early April Fool’s joke. The premise is...

The various projections are just different ways of displaying a three dimensional molecule in two dimensions. They are tools for helping us visualize the molecule and the only time you have to use them would be on a test where they specifically ask you to draw them. That said, Newman projections are useful for figuring out how groups interact when they are bonded to adjacent carbons in a molecule.

The Newman projection of a molecule is a superimposition of the two atoms on a single bond showing dihedral angles between the groups on the front and the back atom.

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.Draw the wedge and dash structures and the Newman projections for each of these conformers (staggered, gauche and eclipsed), labeling each. Staggered Newman: Staggered Wedge-and-Dash: Eclipsed Newman: Eclipsed Wedge-and-Dash: Gauche Newman: Gauche Wedge and Dash: 2. Draw a potential energy surface in your lab notebook i.e. x-y plot of potentialBut it is easiest to compare structures using Fischer projections, because they are always written in the same way. If we make the wedge-dash formula vertical with C-1 at the top, it becomes structure B above. It is then easy to convert B into the Fischer projection A. Here's a video on converting line drawings to Fischer projections.

In the left case the black hydrogen on the left side is pointed up, thus the other one on the right side is pointed down. Wedged bond means the bond is pointing towards us, the dashed bond means the bond is extending behind the plane of the drawing surface.Step 1/4 Step 1: First, we need to understand the Fischer projection. In a Fischer projection, the horizontal lines represent bonds that come out of the plane of the paper (towards you), and the vertical lines represent bonds that go into the plane of the paper (away from you).Predicting the product of a stereospecific E2 reaction by drawing Newman projections is great for explaining the concept, yet time-consuming. So, let me give you a quick tip. To quickly predict the correct stereoisomer of a stereospecific E2 reaction check the wedge and dash of the beta hydrogen and the leaving group:
