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.

The term comes from the Greek root kheir-, hand, and means "handedness." Chiral molecules show left and right-handed nature in the sense that the molecules may exist as mirror-image forms that cannot be made to overlap by any amount of rotation. The main … bungalows for sale rodmill eastbourneIn chemistry, a molecule or ion is called chiral 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 (/kaɪˈrælɪti/). The terms are derived from Ancient Greek χείρ (cheir) 'hand'; which is the canonical example of an object with this property. bungalows for sale rodley leeds
