WebMore importantly, the chiral NCs are aggregated into an infinite double-stranded helix supported by intra-strand homonuclear C‒H···H‒Cdihydrogen contacts and inter-strand C-H/π and C-H/S interactions. The unique multi-layered 3D chirality and the double-helical assembly of Cu18H are evocative of DNA. Moreover, the collective behaviours ...

WebOne of the most interesting types of isomer is mirror-image stereoisomers, a non-superimposable set of two molecules that are mirror images of one another. The existence of these molecules is determined by concept … WebA chiral centre is an atom that has four different groups bonded to it in such a manner that it has a nonsuperimposable mirror image. The term "chiral centre" has been replaced by the term chirality centre. In the molecule below, the carbon atom is a chirality centre. It has four different groups attached, and the two structures are ...

A … WebChirality (chemistry) The term chiral (pronounced /ˈkaɪɹ (ə)l̩/) is used to describe an object that is non-superimposable on its mirror image. Human hands are perhaps the most universally recognized example of chirality: the left hand is a non-superimposable mirror image of the right hand: no matter how the two hands are oriented, it is ...
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.
