Did you know?
Homotopic, simply means identical. For example, all the protons in ethane are homotopic. Even tough each proton is physically different, but we say that they are identical because the rotation about the C-C single bond is so fast that averagely speaking all the protons appear in the same environment. There is … See more The most common set of nonequivalent protons that you will hear bout in your course is going to be the diastereotopic protons. If replacing … See more Replacing the hydrogens in order to determine the relationship of the protons and hence the number of NMR signals may look … See more There one more case scenario – What if neither a plane nor an axis of symmetry reflects two protons and they are not stereochemically related?
