Draw a horizontal line to represent the plane of the paper. 2. Draw the carbon atoms in a vertical line, with the lowest-priority substituent (usually hydrogen) drawn at the back of the molecule. 3.
Fischer projections are just another way of drawing compounds contacting chirality centers. They were initially proposed by Emil Fischer for making it easier to draw the structures of compounds containing multiple chirality centers with the main idea of not having to draw the wedge and dash lines for every single chiral center. 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.
As you can see we have two different ways for the Newman Projection. 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.
