boiling point

[NHolmes3L]

How do you determine high vs low boiling point?

[Reina Robles 2B]

Substances with higher boiling points will have stronger intermolecular interactions. Conversely, substances with lower boiling points will have weaker intermolecular interactions.

I hope this helps!

Stronger intermolecular forces have a higher boiling point. If same IMF, such as LDF, the larger molecule will have a higher boiling point.

[Deepika Reddy 1A]

The stronger the IMFs, the higher the boiling point. For example, it takes more energy to break dipole-dipole IMFs than to break London dispersion IMFs because dipole dipole forces are stronger. Therefore, by looking at the IMFs, we can predict which substances have a higher boiling point.

Substances that have a higher boiling point are more polar and greater IMF, such as dipole-dipole interactions, LDFs, hydrogen bonds, ion-ion, and dipole-induced-dipole.

The boiling point of a molecule depends on its structure. It can depend on the intermolecular forces present between the atoms or molecules and boiling points increase as the size of the molecule increases.

It is also important to remember that boiling does not break bonds. So when explaining the effect that boiling point has, my TA suggested avoiding using the phrase "break bonds" and use "overcome intermolecular forces" instead.

[Kimberly Koo 2I]

When something has stronger intermolecular forces, the boiling point is generally higher. For example, if a molecule has H-bonds, it'll have a higher boiling point than a molecule with only London Dispersion Forces, as LDF are weaker than H-bonds.

[Hussain Chharawalla 1G]

Also remember the respective strength of intermolecular forces. Hydrogen bonds are much stronger than LDF. Ion-dipole then dipole-dipole, etc. etc. Ionic bonds are weak in water.

The boiling point is higher the stronger the intermolecular force is.
