WebAbsolute configuration refers to the spatial arrangement of atoms within a chiral molecular entity (or group) and its resultant stereochemical description. Absolute configuration is typically relevant in organic molecules, where carbon is bonded to four different substituents.This type of construction creates two possible … WebAll three also use single bonds to indicate stereochemistry, with the projection itself implying the stereochemical configuration, rather than hash and wedge bonds. ChemDraw interprets the stereochemistry according to the established conventions of each projection. Below are the same three molecules with chiral centers identified.
