Witryna13 mar 2014 · These intermolecular forces are made possible by a large difference in electronegativity values for two atoms bonded to each other. In water, the electronegativity difference between oxygen (3.5) and hydrogen (2.1) is 1.4 (3.5-2.1=1.4). This, and waters bent shape, make water a polar molecule. Another polar molecules … WitrynaHexane is a non-polar molecule. This is down to 2 factors; firstly, the only bond is C-H, which is non-polar due to carbon and hydrogen having very similar electronegativities, secondly hexane is symetric so any polarity in the molecule would cancel out. …
