How to draw newman projections from wedge dash.
In a Fischer projection drawing, the four bonds to a chiral carbon make a cross with the carbon atom at the intersection of the horizontal and vertical lines. The two horizontal bonds are directed toward the viewer (forward of the stereogenic carbon). The two vertical bonds are directed behind the central carbon (away from the viewer).
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.Draw the Newman projection of 2,3 dimethylbutane along the C 2-C 3 bond. Then determine the least stable conformation. First draw the molecule and locate the indicated bond: Because the question asks for the least stable conformation, focus on the three possible eclipsed Newman projections. Draw out three eclipsed Newman projections as a template.Answer link. You follow a series of steps. > Step 1. Draw the structure of hexane. Step 2. Convert it to a wedge-dash structure at "C-2" and "C-3". Step 3. Identify the groups on "C-2" and "C-3". The main chain of hexane is the horizontal zig-zag line of carbon atoms. "C-1" is on the left. 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. 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.

The conformations of alkanes are the isomers of alkane which are formed when carbon-carbon bond get rotated. The carbon-carbon single bond gets rotated with forming different structures and these structures are studied in the conformations of alkanes. The three-dimensional structure can be easily drawn using the conformations of alkanes.Horizontal lines are wedges which point out of the plane of the paper while the central vertical line has dashes pointing into the paper.

If you have no clear large group on one side of the projection, you’ll just be stuck with projections called staggered (not overlapping) and eclipsed (overlapping). Fischer projection: For acyclic molecules, especially those with many substituents, chemists will use the Fisher projection to make drawing the molecules more rapid. The convention depicts bonds drawn from top to bottom are in the dash conformation while the bonds drawn from left to right are in the wedge conformation.The Newman projection is obtained upon a 90° degree rotation of the dash-wedge structure. It is an end-on representation where the molecule is viewed along the bond of interest, a projected bond. The atom farther from the observer is represented by a circle, and the atom closer to the observer is denoted as the center of the circle. ...
