    "abstract": "Chirality is of primary importance in many areas of chemistry and has been\nextensively investigated since its discovery. We introduce here the description\nof central chirality for tetrahedral molecules using a geometrical approach\nbased on complex numbers. According to this representation, for a molecule\nhaving n chiral centres, it is possible to define an index of chirality.\nConsequently a chirality selection rule has been derived which allows the\ncharacterization of a molecule as achiral, enantiomer or diastereoisomer.",
