Enantiotopic - Study guides, Class notes & Summaries

SI Chapter 9 Handout Differentiating and Counting Signals Classify the relationship between HA and HB in each molecule below as homotopic, heterotopic, enantiotopic, or diastereotopic. (Hint: Some examples may fit multiple definitions) How many proton signals would you see for each of the molecules below? How many carbon signals would you see?

NMR is the most valuable spectroscopic technique used for structure determination.  More advanced NMR techniques are used in biological chemistry to study protein structure and folding.

Asymmetric synthesis is a subclass of stereoselective reactions, where a new chiral stereogenic unit is created during a reaction. The new stereogenic unit can be a chiral centre, a chiral axis or a chiral plane. The reaction must proceed with unequal formation of possible stereoisomers. The chiral unit can be produced from substrates bearing pro-chiral units such as pro-chiral centre, a pro-chiral plane or a pro-chiral axis. The pro-chiral unit can be enantiotopic or diastereotopic. Thus, two e...
