Web- If replacement of two H's, in turn, by a test group generates a pair of enantiomers, those two H's are enantiotopic. - Enantiotopic protons are chemically equivalent. - Enantiotopic protons will give the same 1H NMR signal. Match each structure with the integration ratio each should show in its 1H NMR spectrum (values are listed in numerical ... WebNMR equivalent protons - diastereotopic, enantiotopic, homotopic. While the rules to determine if protons are homotopic, enantiotopic or diastereotpic are quite simple they may be difficult to apply. In this webpage you can draw a chemical molecule and find out where the diastereotopic atoms are. Go over a hydrogen with the mouse to find out ...

WebEnantiotopic Protons: Enantiotopic protons normally have identical chemical shifts. However, when the molecule is placed in a chiral environment (say with an optically active solvent, cosolvent or Lewis acid) then the protons can become diastereotopic. This is in contrast to homotopic protons, which are always identical. Diastereotopic Protons: WebYou'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer. Question: Which of the following is true for pair of enantiotopic protons? 1. 2. They will appear at the same chemical shift in an achiral (i.e., nonchiral environment) They will appear at the same chemical shifts in a chiral environment.
