WebApr 10, 2024 · Fischer projections are a way of drawing molecules in two dimensions. The most important thing to remember when drawing a Fischer projection is that the horizontal lines represent bonds that are coming out of the plane of the paper, and the vertical lines represent bonds that are going into the plane of the paper. This can be a bit confusing, … WebAbout this unit. Just like how your left foot doesn't quite fit your right shoe, molecules also can have properties that depend on their handedness! This property is called chirality. We will go over what makes a molecule chiral, stereoisomers, assigning configurations using the R,S system, optical activity and Fischer projections.
