Chirality chirality
WebIn chemistry, axial chirality is a special case of chirality in which a molecule contains two pairs of chemical groups in a non-planar arrangement about an axis of chirality so that the molecule is not superposable on its mirror image. [1] [2] The axis of chirality (or chiral axis) is usually determined by a chemical bond that is constrained ... WebJan 23, 2024 · Fundamentals of Chirality.

WebYes, chiral comes from the Greek word χέρι for hand. But in a way chirality and chiral symmetry are opposites: Both your hands together are an object with chiral symmetry because "mirror image of two hands" looks the same as "two hands" - though the reflection interchanges the hands, so to speak. On the other, erm, hand, a single hand (your right … Weballows chemists to create helicenes with the desired chirality, and could also be suitable for longer chains of benzene rings.
