Chiral und achiral
WebThe atoms attached to C5 are C, H, H. There is no difference. To decide between C2 and C5, we must go one atom further out. From C2, C3 has F, C, H. From C5, C4 has C, H, H. C2 is therefore #2, and C5 is #3. If you assign these priorities to the groups, the sequence 1 → 2 → 3 goes in a counterclockwise direction (S).

WebDec 27, 2015 · Each of the enantiomers is a diastereomer of the achiral meso compound. Both diastereomers achiral. 2,3,4-Tribromopentane has three chiral carbons, but two of the eight possible stereoisomers are meso compounds because they have an internal plane of symmetry. They are both achiral, but they are still diastereomers of each other. http://www.differencebetween.net/science/difference-between-chiral-and-achiral/#:~:text=A%20chiral%20is%20an%20object%20that%20is%20not,identically%20superimposable%20with%20a%20mirror%20image%20of%20itself.
