WebThe optical isomers are called dextro and laevo depending upon the direction in which plane of the polarized light is rotated. These d and l isomers of compound are called enantiomers. Example is given above. REVISE WITH CONCEPTS Isomerism in Coordination Compounds Example Definitions Formulaes Structural Isomerism in Coordination Compounds WebStructure. Glyceraldehyde has one chiral center and therefore exists as two different enantiomers with opposite optical rotation: . In the D/L nomenclature, either D from Latin Dexter meaning "right", or L from Latin Laevo meaning "left"; In the R/S nomenclature, either R from Latin Rectus meaning "right", or S from Latin Sinister meaning "left" fischer carbonlite classic prisguiden https://tomanderson61.com
