Webdiastereotopic, enantiotopic, or homotopic. Explain your reasoning. a) OH HS H H H Given the presence of one chiral center (of the S configuration), substitution of the two hydrogens respectively gives (S, R) and (S, S)—these are diastereomers, so the hydrogens would have to be diastereotopic. Web3 mei 2024 · Note that these are the pairs which are transformed onto each other under the influence of the 2 rotation. Homotopic protons have the same colour in the image below.
