Understanding the Strength of the Hydrogen Bond

Web27 feb. 2024 · To boil 1 kg of water we need 2.3 x 106 J. Each hydrogen bond requires an input of 0.2 eV to break it. Converting that to Joules we get (0.2 eV) x (1.6 x 10-19 J / 1 eV) = 0.32 x 10-19 J per hydrogen bond. So if all our energy of boiling is breaking hydrogen bonds, we must be breaking. N = (2.3 x 106 J) / (0.32 x 10-19 J/bond) ~ 7 x 1025 bonds.
