WebCan someone tell me if a C-atom can still be Chiral when he has 3 different groups and one is double-bonded? For example: 1-bromo-1,2-dichloroethylene • ( 3 votes) dysmnemonic 10 years ago No; a C atom needs to have four different groups bonded to it to be chiral. In that example, the molecule will instead have E/Z isomerism across the double bond. 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).
