Abstract
If a chiral substance is prepared from achiral precursors, the first chiral molecule represents obligatorily 100 percent enantiomeric excess. Similar cases can be identified at the degradation of a racemate, for the last chiral molecule and the one-molecule excess obligatorily formed if a racemate contains an odd number of molecules. These cases have a particular significance in speculations regarding the origins of biological chirality and the molecular-level events in chiral autocatalysis.
