WebSummary: Topicity describes relationships between localised areas in the same molecule. Homotopic groups are those that can be interconverted by a proper rotation and are chemically identical If either homotopic group were replaced by the same substituent the resulting molecules would be the same. WebDifference between homotopic, Enantiotopic, and Diastereotopic protons explained … Web1 jul. 2024 · To determine if protons are homotopic or enantiotopic, you can do a thought experiment by replacing one H with X followed by the other H by X. In pyruvate below, if you replace any of the Hs with an X, then you would get the same molecule. These protons are homotopic.

WebEnantiotopic Atoms: The methyl hydrogens of ethanol are homotopic but the hydrogens of the methylene group are heterotopic, i.e., different (H6 and H7; see above). In this instance they are enantiotopic. If you pass a plane through the two carbons and the hydroxyl group, the two hydrogens of the methylene group occupy enantiomeric positions.

All the others are … 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.

Web19 feb. 2024 · You determine by labeling. Take the two hydrogens in question and label them one at a time to get two molecules. What's the relationship between these two molecules? If the molecules are the … WebFor example the two groups c in a grouping Cabcc are enantiotopic. Replacement of one of a pair of enantiotopic groups forms one of a pair of enantiomers. Analogously, if complexation or addition to one of the two faces defined by a double bond or other molecular plane gives rise to a chiral species, the two faces are called enantiotopic.

Web22 sep. 2024 · To determine the relationship of these protons, remember that symmetry axis means homotopic, and if there is no axis, but a there is a plane of symmetry, then the protons are enantiotopic. If the protons are not related by these symmetry elements, they are not equivalent and will give two NMR signals.
