Temperature dependence of the shear viscosity measured for isotropic liquids belonging to the three homologous series: 4-(trans-4'-n-alkylcyclohexyl) isothiocyanatobenzenes (C_n H_{2n+1} CyHx Ph NCS; nCHBT, n=0÷12), n-alkylcyanobiphenyls (C_nH_{2n+1} Ph Ph CN; nCB, n=2÷12) and 1,n-alkanediols (HO(CH_2)_nOH; 1,nAD, n=2÷10) were analysed with the use of Arrhenius equation and its two modifications: Vogel-Fulcher and proposed in this paper. The extrapolation of the isothermal viscosity of 1,n-alkanediols (n=2÷10) to n=1 leads to an interesting conclusion concerning the expected viscosity of methanediol, HOCH_2OH, the compound strongly unstable in a pure state.
