WebFischer projections are a way to represent three-dimensional molecules in two dimensions. By following specific rules for drawing these projections, one can depict complex … Web2 years ago. Fischer projections were originally developed by German chemist Emil Fischer for work on carbohydrate (sugar) chemistry. It's a way to quickly draw multiple sugars and compare them since it's easy to spot the asymmetric carbons on a Fischer projection. In fact the example which Jay uses in the video is a sugar called …

WebJan 23, 2024 · The Fischer Projection consists of both horizontal and vertical lines, where the horizontal lines represent the atoms that are pointed toward the viewer while the vertical line represents atoms that are pointed away from the viewer. The point of intersection between the horizontal and vertical lines represents the central carbon. WebAssigning R and S Configurations to Fischer Projections 1. Assign priorities to the four substitutents according to the Cahn-Ingold-Prelog rules 2.

WebCollege of Arts and Science Vanderbilt University WebOrganic Chemistry Newman Projections When atoms in organic molecules connect via single bonds, you can have a free rotation around those single bonds. That gives you a different 3D forms of the same molecule. We refer to those forms as conformations of the molecules. These molecular conformations may be somewhat challenging to represent. …
