You will see that n-butanol is not very polar (in the sense of dipolar bonding), but that it is higly capable of hydrogen bonding; while ethyl acetate is about the same polarity, but poorer in terms of hydrogen bonding. Water is a polar molecule because the electronegativity of oxygen is higher than that of hydrogen, meaning that the electron density is shifted towards the oxygen atom in the molecule. ; Sanchez, L.G., Polarity of the Gas Chromatographic Stationary Phases and Retention Indices of Aliphatic Esters, Ketones and Alcohols, Anal.

There are molecules with a nonpolar bond but are polar molecules by nature (examples: NCl3, ozone, water). Its essential for predicting molecular geometry, molecule polarity, and reactivity in a compound. Out of the first two, they are both polar but the iodide one has a much bigger mass 126 vs oxygen 16 or nitrogen 14. lar nn-p-lr : not polar especially : consisting of molecules not having a dipole a nonpolar solvent Example Sentences Recent Examples on the Web The remaining nonpolar molecules in food - like fats and minerals - are not heated by the microwaves themselves. 25 Jun. 1.1, California Environmental Protection Agency, Air Resources Board, El Monte, California, 1997, 22. ass: Standard non-polar; Column diameter: 0.25 mm; Column length: 60 m; Column type: Capillary; Heat rate: 2 K/min; Start T: 30 C; End T: 220 C; Start time: 4 min; CAS no: 71363; Active phase: DB-1; Phase thickness: 0.25 um; Data type: Kovats RI; Authors: Takeoka, G.; Perrino, C., Jr.; Buttery, R., Volatile constituents of used frying oils, J.
