WebFischer 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. The carbon chain is then positioned vertically upward with all horizontal attachments pointing toward the viewer. WebNewman projections are another system that can be used as they showcase the structure of a molecule in the staggered or eclipsed conformation states.

For this, we need a 180 o rotation … 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 ...

WebJul 16, 2024 · Rule 1: Rotation of the Fischer projection by 90º in either direction changes the absolute configuration at the chiral center. Rule 2: Interchanging any two ligands on the chiral center changes the absolute configuration at the chiral center. The above rules assume that the Fischer projection under consideration contains only one chiral center.
