WebMar 26, 2009 · Many apparently achiral organic molecules on Earth may be chiral because of random substitution of the 1.11% naturally abundant 13 C for 12 C in an enantiotopic moiety within the structure. However, chirality from this source is experimentally difficult to discern because of the very small difference between 13 C and 12 C. We have … WebSupplemental Topics.

WebTopicity. In chemistry, topicity is the stereochemical relationship of substituents relative to the structure to which they are attached. Depending on the relationship, such groups can be homotopic, enantiotopic, or diastereotopic . The stereochemical term enantiotopic refers to the relationship between two groups in a molecule which, if one or the other were replaced, would generate a chiral compound. The two possible compounds resulting from that replacement would be enantiomers. For example, the two hydrogen atoms attached to the second carbon in butane are enantiotopic.
