Two views of the enantiomers of this interesting molecule are displayed below. Some objects are highly symmetric and incorporate many symmetry elements. Such an object is necessarily chiral. In contrast, if a counterclockwise turn moves the helix away it has a minus or M configuration, sometimes called Sa or Sh. For the ansa compound, this leads to the aromatic carbon atom bound to bromine as c. Finally, the absolute configuration is called Sp or M if the atom sequence abc, viewed from above the Pa bond, describes a counterclockwise arc.

Generate Phase Diagram. See Example 13.16. Due to strain, neither of these groups is truly coplanar, as may be seen in the three-dimensional models available below. Thus, depending on the number of such units linked together, the terminal substituents will either be orthogonal or coplanar. Kooper Davis Death Hobbs, Nm, Symmetry Resources at Otterbein University. The configurational stability of such isomers depends on the energy barrier to rotation about the single bond connecting the rings, and this in turn is proportional to the size of the ortho-substituents on each ring. The following diagram illustrates the structural relationship of a disubstituted tetrahedral carbon (Ca2b2) to an allene (top row), and a disubstituted alkene (abC=Cab) to an analogous 1,2,3-cummulene.

Since no chiral center exists in this molecule, its chirality is due to the dissymmetric orientation of substituents about a chiral axis (the axis defined by the three carbon atoms of the double bonds). A center or point of symmetry is labeled i, and the inversion operation demonstrates coincidence of each atom with an identical one on a line passing through and an equal distance from the inversion point (see chair cyclohexane).
