anonymous · Answer

i think the right chain of option C is longer so  it has the lowest dissociation ! i am not sure i think

anonymous · Answer

it has to do with the position of the halogen.  closer to the carboxyl group makes the molecule more polar (negative at that end of the molecule) and thus harder for the proton to leave (dissociate).
