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). WebCompound 1 has a chiral carbon center, because it is attached to four different groups (W, X, Y and Z). Compound 2 is the mirror image of compound 1.As per our definition of chirality, compounds 1 and 2 should be non-superimposable. How do we confirm this? …
