Hi. Benzene (or C6H6) is a NONPOLAR molecule because all the individual bonds are nonpolar and C6H6 has symmetrical geometry. Var. Benzophenone [essentially nonpolar (slightly polar due to the C=O bond)] was soluble in methyl alcohol, but only partially . For example, water is a polar liquid and it does not like to mix with nonpolar liquids. It is usually designated by a Greek letter ''. 2), 2003. umn class: Standard non-polar; Column diameter: 0.2 mm; Column length: 50 m; Column type: Capillary; Start T: 60 C; CAS no: 71363; Active phase: HP-101; Carrier gas: H2; Phase thickness: 0.2 um; Data type: Kovats RI; Authors: Garay, F., Application of a flow-tunable, serially coupled gas chromatographic capillary column system for the analysis of complex mixtures, Chromatographia Sup., 51, 2000, s108-s120.
