WebStep 1: Types of protons. Homotopic means identical. If replacing two protons with a different group (X) gives the same compound then protons are homotopic. If by replacing two protons with two different groups if the pair shows an enantiomeric relationship then protons are enantiotopic. If replacing two protons with different groups gives a ... WebHowever, not all neighboring protons are coupled. Signal splitting occurs only between nonequivalent protons. It is not observed for homotopic and enantiotopic protons since they are chemically equivalent. For example, starting with simple methane and ethane, both have equivalent protons which do not split each other, and the signal appears a ...
