Stereochemistry Terms

Chiral A molecule is chiral if it is not superposable on its mirror image.Chiral centers are Carbon molecules with four unique groups attached Enantiomers Stereoisomers that are non-superposable mirror images. Stereoisomers Isomers which have atoms that differ only by their orientation in space. Unlike constitutional isomers, corresponding atoms in stereoisomers exhibit the same connectivity. Isomers […]
