Chirality priority

WebCarboxylate has higher priority as it is attached to oxygen. Hydrogen has lowest atomic number Assigned # 4. If two or more ligands are bonded to the chiral center by atoms that are isotopes (e.g. H, D and T), use the mass number of the isotopes to determine the priority numbers of those ligands WebPrioritize the four groups around a chiral center according to atomic number. The highest atomic number is assigned priority #1, and the lowest atomic number is assigned priority #4. 2. Orient the chiral centre such that the #4 priority substituent is pointing away from the viewer. For our purposes, it’s enough for it merely to be attached to ...

Webfrom the observer and the other three groups have a priority sequence X→Y→Z in a clockwise direction, the chiral center will have a R configuration; otherwise it is defined as an S configuration. The R/S system can be used for other chiral molecules without a chiral center (e.g., planar chirality) as well [6].
