Explain how to draw a Fischer projection, and explain why Fisher projections were developed. Here is one important thing you need to remember when adding the hydrogens or other groups on the zig-zag of the main carbon skeleton. When the zig-zag angle is pointing up, you must point the wedge and dash groups up. When the angle is pointing down, you draw the wedge and dash group down as well: The same principle is applied to larger and ... 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. 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). Step 1.
