Enantiomers are a pair of molecules that exist in two forms that can not be superimposed on each other but are mirror images of each other. Enantiomers have a Chiral Carbon. A Chiral Carbon is a center of Carbon that is bound to four distinct atoms or groups. The existence of Chiral Carbon is referred to as Chirality (in a molecule).

Enantiomers - Definition, Structure, Properties

WebIn chemistry, a molecule or ion is called chiral (/ ˈ k aɪ r əl /) 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 (/ k aɪ ˈ r æ l ɪ t i /).
