A substance with strong hydrogen bonding will have a higher boiling point compared to a substance with weak London dispersion forces.Hydrogen bonding is a strong intermolecular force that occurs when a hydrogen atom is bonded to a highly electronegative atom such as nitrogen, oxygen, or fluorine and is attracted to another electronegative atom in a neighboring molecule. This strong attraction between molecules requires a significant amount of energy to overcome, resulting in a higher boiling point.On the other hand, London dispersion forces are the weakest type of intermolecular forces, arising from temporary fluctuations in electron distribution around molecules. These forces are generally weaker and require less energy to overcome, leading to a lower boiling point.In summary, a substance with strong hydrogen bonding will have a higher boiling point than a substance with weak London dispersion forces due to the stronger intermolecular forces present in the former.
