WebMolecules with a simple tetrahedral geometry can be easily rotated in space so that this condition is met (see figures). Fischer projections are commonly constructed beginning with a sawhorse representation. To do so, all attachments to main chain carbons must be rotated such that resulting Newman projections show an eclipsed configuration. WebA Fischer projection is always in the eclipsed conformation. To draw the sawhorse projection of an eclipsed conformation, start out by first drawing a line representing the carbon-carbon bond sloping upward and to the right (Pause the video as you trace these steps). Then draw one bond in front and one in back exactly straight down. Next, add ...
