Stereocenter vs. Stereocentre
Stereocenter
In a molecule, a stereocenter is a particular instance of a stereogenic element that is geometrically a point. A stereocenter or stereogenic center is any point in a molecule, though not necessarily an atom, bearing different substituents, such that interchanging any two substituents leads to a stereoisomer.
Stereocentrenoun
(chemistry) Any atom in a molecule such that the interchange of two of its substituent groups leads to the formation of a stereoisomer
