1) Lacking a dipole 2) Nonionic 3) Not ionic 4) Temperate 
Having a relatively even or symmetrical distribution of charge.
Having no poles.Used to refer to a bond or molecule that overall has no separation of electrical charge.
<chemistry> Describes a molecular that does not have a permanent electric dipole and consequently may be less soluble in water (for example lipids). ... See: nonpolar groups ... (12 Mar 1998) ... 
(non-po´lәr) not having poles; not exhibiting dipole characteristics.
Having no concentrations of electrical charge on a molecular scale, thus, incapable of significant dielectric loss. Examples among resins are polystyrene and polyethylene.
containing no permanently dipolar molecules; lacking a dipole.
