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.

WebEnantiomers are much like one's right and left hands, when looking at the same face, they cannot be superposed onto each other.
