A calculation of the optical activity of the α-1,2,3,4,5,6-Hexahalocyclohexane is presented based upon the Kirkwood's polarizability theory of optical rotatory power. The calculated specific rotation of the compound are given in the following table. α-1,2,3,4,5,6-Hexahalocyclohexane [α]D cal [α]D obs. e e e e a a (Cl) -18.3 -14.6 in ether e e e e a a (Br) -19.8 -14.6 in ether-acetone e e (Br) e e a a (Cl) -18.6 -14.7 in ether e e e e (Br) a a (Cl) -17.5 -10.4 in ether e (I) e e a a e (Cl) -18.2 -19.0 in ether-acetone The close agreements demonstrates the applicability of the polarizability theory to the compounds whose optical activity is due to steric interference. The agreement in sign also confirms the validity of the absolute configuration of the α-1,2,3,4,5,6-Hexahalocyclohexane given by O. Hassel.
