Non-uniqueness of the true stereoisomers generated by binary enumeration. Both of the molecules depicted, ClC(Br)CC(Br)Cl and BrC=CC=CBr, possess two true stereocenters. There are thus \(2^2=4\) possible binary configuration vectors. The corresponding stereoisomers are shown for the two molecules. In both cases, however, only three stereoisomers are unique. For the stereoisomers on the top, the stereoisomer with configuration vector [0,0] (leftmost) is identical to that with configuration vector [1,1] (rightmost). For the stereoisomers on the bottom, the stereoisomer with configuration vector [0,1] (left of center) is identical to that with configuration vector [1,0] (right of center)
