This was so brief, simple, and understanding

In reply to Peter. Certainly. To take a simple example, (R,S)-1,2-cyclohexane diol. Every methylene (i.e. CH2) carbon in that molecule bears a pair of diastereotopic protons.

For meso compounds, can they still have diastereotopic protons?

In reply to George. Fixed. Thank you George!

It’s really helpful, clearly described..I want some examples on diastereotpic faces of alkenes with symmetry and addition criterion

Yes – thank you, and you are right, it does refer to an earlier version!

Very clear descriptions but your Enantiotopic figure is described as butane but is still ethane so the figure itself is Homotopic. Also your descriptions often are of a chlorine replacement but the figures are still of deuterium (an earlier version?).

I bought your spectroscopy pdf but haven’t had a chance to read it yet…. but your site has been so helpful figured I try it!
