nonpolar

 [non-po´lar]
not having poles; not exhibiting dipole characteristics.

nonpolar

[-pō′lər]
Etymology: L, non + polus, pole
pertaining to molecules that have low polarity and have a hydrophobic affinity, tending to exclude or avoid water. Nonpolar substances tend to dissolve in nonpolar solvents. Compare polar.

nonpolar

Of a molecule or molecular region in which the chemical bonds share electrons equally so that there are no externally operative electric charges.

nonpolar

(of a substance) bearing no charge or hydroxyl groups, and thus not combining with water.

nonpolar

not having poles; not exhibiting dipole characteristics.
