The symmetry of a molecule is determined by the existence of symmetry operations performed with respect to symmetry elements. 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. What is the symmetry group of the biphenyl when the torsional angle between the phenyls is 20 degrees? Chemists classify molecules according to their symmetry. An improper axis, Sn, consists of a n-fold rotation followed by reflection through a mirror plane perpendicular to the rotation axis (n is always 3 or larger because S1 = and S2 = i).
