Molecular polarisability: the conformations of tetrahydropyran and 2-chlorotetrahydropyran as solutes in carbon tetrachloride

Abstract

The dipole moments, molar Kerr constants, refractivities, etc. are reported for tetrahydropyran and 2-chlorotetrahydropyran as solutes in carbon tetrachloride. A comparison of the observed dipole moments and molar Kerr constants with values calculated from bond moment and polarisability data for rival space formulae indicates that the preferred solute conformation of tetrahydropyran has a chair ring, and that of 2-chlorotetrahydropyran, a chair ring with an axially disposed C–Cl bond.
