Web6 okt. 2024 · SUMMARY Between homotopic groups and faces no differentiation is possible either by enzyme or by NMR or by human being because they are homomers or … Let’s look at butane next; specifically, the second carbon of butane. Replacement of the red H with D leads to (R)-2-deuteriobutane, while replacement of the blue H with D leads to (S)-2-deuteriobutane. … Meer weergeven Take a molecule like ethane. Let’s label (with color) two different hydrogens, blue and red. Next, let’s replace each of these hydrogens in … Meer weergeven It’s also possible to have diastereotopic protons. Look at the alkene below. Replacement of the red H with D leads to the E-alkene, while replacement of the blue H with D … Meer weergeven
