This is due to : The bond in the molecule is C-H, which is non-polar in nature because the carbon and the hydrogen having very similar electronegativity values. H2O and HF will be the strongest out of these options. Therefore, we can compare the relative strengths of the IMFs of the compounds to predict their relative boiling points. The most pronounced and consequential intermolecular forces at play has to be hydrogen bonding due to the dipole created between the oxygen and hydrogen in the hydroxyl group. 15 January 2013 1 Intermolecular Forces!
