1. The problem statement, all variables and given/known data I've attached a picture of the molecule. The question: at which molecules (s) would it be likely that there would be a nucleophilic attack? 2. Relevant equations 3. The attempt at a solution The answer key says a and c, only. However, I think that b is nucleophilic because the nucleophile can attack the alkene carbon furthest from the bromine, which would shift the alkene up, knocking off the bromine.
