Review - 6Fluorine has a larger electronegativity than oxygen, so the H-F bond is more polar than the H-O bond. This means that individual hydrogen bonds between H-F molecules are stronger than individual hydrogen bonds between H2O molecules. However the effects of hydrogen bonding on the properties of water (unexpectedly high normal boiling point, the low density of solid water compared to liquid water) are much more pronounced than for HF. Why is this so? HintThe overall strength of hydrogen bonding in a substance is determined by the strength of the individual bonds and the total number of bonds which can form between the molecules.
