A series of 1-(trans-4 prime -n-alkylcyclohexyl)-2-(4 double prime -halobiphenyl-4 prime -yl)ethanes, which show nematic phases, was prepared. Their transition temperatures, enthalpies and entropies were measured. Their bulk viscosities, birefringences and dielectric constants were determined by extrapolation. The bulk viscosity as a function of the third power of the van der Waals radius of the halogeno group, the birefringence as a function of the van der Waals radius of the halogeno group, and the dielectric constants as a function of the dipole moment of the halogeno group are discussed for the 1-(trans-4 prime -n-propylcyclohexyl)-2-(4 double prime -halobiphenyl-4 prime -yl)ethanes.
