Mnemonic in Stereochemical Nomenclature Teaching
Charles University in Prague, Faculty of Chemical Education, Department of Chemistry and Chemical Education
The chemical mnemonic devices enabling students to assign the appropriate configurational descriptor to a stereogenic unit – double bond (cis/trans, E/Z), stereogenic centre (R/S), stereogenic axis (Ra/Sa, P/M) and prostereogenic centre (pro-R/pro-S) – are gathered and discussed. In addition to the inspection of stereoformula, some other mnemonics are included, e.g. the „Rule of Multiplication“, the „Right-Hand Rule of Organic Chemistry“, the „Vertical-4-Verity Rule“, the „Very good Fischer Projection“ and so on. All these devices are applicable both to the perspective formulas and to the Fischer projection formulas.
