Enantiomer - Wikipedia

Enantiomers, also known as optical isomers, are two stereoisomers that are related to each other by a reflection: they are mirror images of each other that are non-superposable. Human hands are a macroscopic analog of this. Every stereogenic center in one has the opposite configuration in the other. Two compounds that are enantiomers of each other have the same physical properties, except for the direction in which they rotate polarized light and how they interact with different opt… WebOptical isomers are a pair of molecules with non superimposable mirror images, such molecules are known as chiral molecules The compounds which rotate the plane polarised light to the right are known as dextro and to the left are known as leavo compounds Square planar complexes do not exhibit optical isomerism imperial porcelain teawareWebEnantiomers are in every other respect chemically identical. A pair of enantiomers is distinguished by the direction in which when dissolved in solution they rotate polarized light, either dextro (d or +) or levo (l or -) rotatory; hence the term optical isomers. imperial porcelain wedgwood
