WebAug 29, 2014 · Stereocenters are labeled R or S. The "right hand" and "left hand" nomenclature is used to name the enantiomers of a chiral compound. The stereocenters are labeled as R or S. Consider the first picture: a curved arrow is drawn from the highest priority ( 1) substituent to the lowest priority (4) substituent. WebIn the simplest case, a compound with two chirality centers where there is the same set of four groups at each chirality center, the combination where the four groups are arranged such that the centers are mirror images of each other (i.e. where the molecule has an internal mirror plane) is a meso compound.

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.
Chirality is an asymmetric quality that is relevant in many fields of science. The word chirality comes from the Greek (kheir), which means “hand,” a common chiral item. A chiral item or system is distinct from its mirror image; that is, it cannot be overlaid onto it.

Diastereomers are not mirror images of each other and are non … See more In chemistry, an enantiomer is one of two stereoisomers that are mirror images of each other but cannot be superposed, similar to how one’s left and right hands are mirror images of … See more WebVideo transcript. the RS system is used to describe the configuration of a chirality center. Down here we have a pair of enantiomers. On the left we have one compound, on the right we have its mirror image. We're going to assign an R orS to each of our enantiomers so let's start with step one.

The term chirality has derived from a common chiral entity, which is the Greek “side”. If it is distinguishable from its mirror image, a system or entity is chiral; that is to say, it cannot be superimposed over it.
