Fischer projection practice
WebFeb 13, 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.

WebThe way I like to think about the Fischer Projection is like a stick man wearing a bow-tie facing you. The bow-tie is the horizontal line, and the guy is the vertical line. Like the lobes of a bow-tie come out towards you, so do the groups attached in the horizontal line. The vertical line leans away from you, not 180 degrees opposite, but just ... WebStep 2.
