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. WebJun 14, 2014 · Chiral objects are objects that are not superimposable on their mirror images.
