WebMar 31, 2024 · Chirality is defined as a property of an object that is asymmetric and cannot be superimposed on mirror images. Chiral center is defined as an atom that consists of four different groups attached to an atom and cannot be superimposed over mirror images. 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).
