Enantiotopic chemistry

WebEnantiotopic groups are chemically identical groups that can be interconverted by an improper rotation. If either enantiotopic group were replaced by the same substituent the resulting molecules would be the enantiomers of each other. Key Words: Webenantiotropic: [adjective] of, relating to, or exhibiting enantiotropy.

Enantiotopic and Diastereotopic Hydrogens in Organic Chemistry

WebProtons and carbon nuclei exchanged (only) by a mirror plane, are said to be enantiotopic (i.e. interchanged by an improper axis of rotation). Enantiotopic nuclei are equivalent (i.e. isochronous), and should give rise to the same chemical shifts in … WebIllustrated Glossary of Organic Chemistry.

WebEnantiotopic Definition: Protons that are not interchangeable by rotational symmetry but are interchangeable by reflectional symmetry. Enantiotopic Explained: Constitutionally … WebEnantiotopic protons are two protons present in achiral molecule that are identical due to the presence of mirror plane. When they are replaced by another group, it results in the formation of chiral molecule. These protons are identical in every aspect excluding the fact of being in a chiral environment.

WebJan 13, 2015 · Prochiral hydrogens can be designated either enantiotopic or diastereotopic. If either HR or HS on ethanol were replaced by a deuterium, the two resulting isomers would be enantiomers (because there are no other stereocenters anywhere on the molecule). Thus, these two hydrogens are referred to as enantiotopic. simplicity 8031The 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.
