Chirality molecules
WebJan 3, 2015 · A molecule is considered chiral if there exists another molecule that is of identical composition but which is arranged in a non-superposable mirror image. Also the presence of an asymmetric carbon … WebMolecules with a single chirality centre are chiral. Molecules with more than one chirality centre are usually chiral. The exceptions are meso compounds. For example, tartaric acid has two chirality centres, so you would expect it to have #2^2 = 4# stereoisomers. But there are only three isomers.

WebAbstract. Chirality plays a central role in the world around us, with nature and scientists producing an ever-increasing number of chiral molecules that have a wide range of different applications. The word chirality is used as a term to describe a molecule whose enantiomers are non-superimposable on their mirror images.
