Boiling points of Hydrogen bonds

[Azlyn Hernandez 2E]

How do hydrogen bonds across different molecules affect the boiling points and how can we compare them?

[Hannah Cole 3J]

Hi there! Hydrogen bonding across different molecules increases boiling points by enhancing intermolecular forces. Molecules capable of forming hydrogen bonds generally have higher boiling points compared to similar molecules that lack this bonding interaction. The strength of hydrogen bonding depends on the electronegativity of atoms involved and the ability to form strong dipoles. Larger molecules still exhibit higher boiling points due to increased molecular mass, but the impact of hydrogen bonding is significant. The number and strength of hydrogen bonds, along with molecular mass, collectively determine and can be used to compare boiling points between different molecules. Hope this helps a bit.

hydrogen bonds between molecules significantly raise boiling points by creating stronger intermolecular attractions compared to substances without hydrogen bonding. When comparing substances, molecules that can form hydrogen bonds tend to have higher boiling points than those lacking this capability, even if they have similar molecular weights.
