WebIn 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). WebNewman projection on left; Fischer projection on right. 1. Draw methane (half of ethane's structure) To draw a Newman projection, we first draw the moiety at the "back" of the projection, then draw the moiety at the "front", then connect the two and arrange them into a Newman projection. In the case of ethane, the two moieties are identical, so ... patterson cs
