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.There are two kinds of Newman projections: Staggered and Eclipsed. Staggered conformation is always more stable and lower in energy than eclipsed. When two big groups in the staggered conformation are next to one another, this is called gauche (less stable due to the groups bumping into one another). When two groups are opposite of one another ...Sawhorse to Newman Projection: The conversion of sawhorse to Newman projection is also easy.

Step 1. Find the longest continuous chain of carbon atoms. There is one C atom at the centre of the circle and a second one hidden at the back of the circle. A methyl group off the back adds a third C atom. On the front carbon, the ethyl group has the longest chain, for another two C atoms. We draw a 5-carbon chain.
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).The Fischer projection of L-xylose is. Here's how to convert the wedge-dash structure of L-xylose to its Fischer projection. Step 1. Arrange the molecule so that the chiral carbons and the longest continuous chain are in a vertical line.
