Chirality and achirality
WebTo the best of our knowledge, the dipole induced chirality and achirality have been rarely reported, and the synergistic forces of dipole–dipole and hydrogen bonding interactions on dominating 2D assembly have never been proposed. In addition, structural transition between the Knot-like and Wheat-like configurations can be regulated by ... WebThe latter modulation derives from packing constraints associated with nonlinear molecules—a chiral, locally-polar structural organization indicative of a new type of nematic phase. ... (~10 nm)—despite the achirality of the ~3 nm-long dimers. This is one example of a category of mirror-symmetry-breaking phenomena identified in liquids and ...

WebIn general, if you have a small molecule with no sp3 centers in the molecule, the molecule is planar. But there are many exceptions. Here are a few common ones: - Water is planar. The oxygen is sp3 but there are only 3 atoms so there's nothing to stick out of the HOH plane. - Allene is not planar. WebChiral. Achiral. 1. Chiral molecules are asymmetric. Achiral molecules are symmetric. 2. Chiral molecules are non-superimposable mirror images of each other. Achiral …
