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. WebFor example, lets determine the configuration of the chiral carbon in the following Fischer projection: Step 1. Draw the horizontal bonds as wedge lines: Step 2. Assign the priorities of the four groups: WebTwo important hexoses, in the Fischer projection. In chemistry, a hexose is a monosaccharide (simple sugar) with six carbon atoms.

WebVisualizing a Fischer projection. In chemistry, the Fischer projection, devised by Emil Fischer in 1891, is a two-dimensional representation of a three-dimensional organic molecule by projection. Fischer projections were originally proposed for the depiction of carbohydrates and used by chemists, particularly in organic chemistry and biochemistry. WebFischer Projections provide aid in visualizing chirality as well as where substituents are oriented within space which is why their application can be useful to many. Chirality …
