How to draw newman projections from wedge dash
A compound must have at least two chiral centres to have diastereomers. Let's look at a Compound "A" with two chiral centres. "C2" and "C3" are chiral centres. If we change the configuration at "C2", we get Compound "B". This is not a mirror image of "A", nor is it superimposable with "A". It is a diastereomer of "A".Oct 11, 2014 · http://leah4sci.com/newman-projections/ Presents: Newman Projection to Bond-Line Notation Trick - No model kit required!Struggling with Orgo?

When the angle is pointing down, you draw the wedge and dash group down as well: The same principle is applied to larger and ...
To show stereochemistry, we must use wedge-dash formulas. These formulas give the stereochemical information. But 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.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 Newman projection consists of a circle or a point that represents the carbon-carbon bond and two lines which represent the substituents attached to each carbon atom. In contrast, the wedge and dash notation uses solid wedges and dashed lines to indicate whether a substituent is coming out of or going into the plane of the paper, respectively.
