5.3 Chirality and the R/S Naming System – Organic Chemistry I

WitrynaIn chemistry, a molecule or ion is called chiral (/ ˈ k aɪ r əl /) if it cannot be superposed on its mirror image by any combination of rotations, translations, and some conformational changes. This geometric property is called chirality (/ k aɪ ˈ r æ l ɪ t i /). The terms are derived from Ancient Greek χείρ (cheir) 'hand'; which is the canonical … WitrynaNext ».
