WebJul 20, 2016 · chiral: [adjective] of or relating to a molecule that is not superimposable on its mirror image. WebFeb 4, 2024 · The most stable chair conformation is the one in which the largest groups occupy equatorial positions. In aldohexoses, the CH 2 OH group is the bulkiest substituent, so the most stable chair conformation will be the one in which this group occupies an equatorial position. This is the case for the chair conformation shown to the left. 7. Extra ...

WebIn 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 example of an … WebFinally, by lifting one carbon above the ring plane and the other below the plane, a relatively strain-free chair conformer is formed. This is the predominant structure adopted by …
