The main attention is focused on the kinematic shear viscosity of argon, nitrogen, benzene and nitrobenzene which have different molecular shapes and sizes and intermolecular interactions, as well. We show that all these liquids demonstrate the argon-like behavior of their kinematic shear viscosities and belong to the same similarity class. Additionally, we show that the kinematic shear viscosity of argon is mainly determined by the packing factor which is characteristic for the van der Waals equation of state. We suggest the explicit formula for the shear viscosity. We found out that the similarity in the behavior of the shear viscosities of low-molecular liquids is connected with the identical structure of their averaged interparticle potentials for enumerated and other low-molecular liquids. This circumstance is a consequence of rotational motion of molecules in liquids.
