How To Draw Fischer Projections In Chem Sketch. Glyceraldehyde is an aldose monosaccharide. To determine the R and S configuration of the chiral carbon atoms in a Fischer projection we need first recall the concept of the Fischer projection. As an example if you are asked to draw the enantiomer of the following molecule with three chiral centers you can draw an imaginary mirror plane and draw the reflection of the molecule which is achieved simply by swapping the two group of a chiral center. Many questions about drawing Fischer projections in Organic Chemistry require you to go from a Fischer projection to a bond line drawing.

12 10 pts a The Fischer projection of D-Galactose is given below. Note that the bond line formula gives no stereochemical information. In a fischer projection drawing the four bonds to a chiral carbon make a cross with the carbon atom at the intersection of the horizontal and vertical lines. As an example if you are asked to draw the enantiomer of the following molecule with three chiral centers you can draw an imaginary mirror plane and draw the reflection of the molecule which is achieved simply by swapping the two group of a chiral center. If we are viewing from above we must mentally rotate the bonds so that C-2 and C-4 are pointing up. Now to make a cyclic hemiacetal from your linear Fischer projection youll need to follow a few simple steps.
The horizontal groups are pointing towards the viewer wedge and the groups on the vertical axis are pointing away from the viewer dash even though all the bonds are shown in plain lines.
