This will result in the denatured ethanol containing trace amounts of dissolved benzene. Though benzene is non polar, it does have a polar plane to it. Being an aromatic ring it is polarized across the faces of the ring.

C-C bonds are not polar, and C-H bonds are hardly polar at all, so the dominant IMF in this part of the molecule is London dispersion or induced dipole-induced dipole interaction. That''s a pretty weak interaction generally, but it can get a little stronger between large molecules, or between flat ones, because two flat molecules can have more surface area in contact with each other.

Is 1-butanol polar or nonpolar? - Quora

1-butanol or Butan-1-ol has the formula CH3-CH2-CH2-CH2-OH. While the OH part is polar, we have non-polar C4H9 attached to it. Greater the hydrocarbon portion, more non-polar it becomes. Its lower homologues ( Methanol, Ethanol and Propanol) have lesser hydrocarbon portion and are therefore more polar and water-soluble.
