WebIntroduction to Fischer Projections. The wedge and dash representations of stereochemistry can often become cumbersome, especially for large molecules which contain a number of stereocenters. An alternative … WebFischer projection, method of representing the three-dimensional structures of molecules on a page, devised by Emil Fischer. By convention, horizontal lines represent bonds projecting from the plane of the paper toward the viewer, and vertical lines represent bonds projecting away from the viewer.
WebFischer projections are written as vertical and horizontal lines. The carbon backbone is the vertical line, and the other substituents are horizontal. We assume that the horizontal bonds are coming out towards you (↓). This convention makes it easier to draw and to assign configuration to the chiral centers (this structure is S). ...
