boiling point

[Megan Bundy 2K]

how do we determine, using the intermolecular forces, which molecule is going to have the higher/lower boiling point?

[Harsimer Bal 3K]

Hi! Stronger IMFS between molecules means that the molecule will have a higher boiling/melting point because more energy is required to break those bonds than molecules with weaker IMFS. So, molecules with ion-dipole interactions will have the highest melting/boiling point because they are the strongest IMF while molecules with induced dipole-induced dipole interactions (LDFs) will have the lowest melting/boiling point out of all IMFS because they are the weakest interaction.

[Erin Chin 1L]

Hi there! Molecules with stronger intermolecular forces will have higher boiling points because the more they stick together, the more energy it will take to break them apart. The strongest intermolecular force is ion-dipole, followed by hydrogen bonding, then dipole-dipole, and then induced-dipole induced dipole (dispersion forces). If molecules have the same intermolecular forces, then size and shape can be used to determine the highest boiling point.

[Mihir Sukhatme 1D]

Molecules with very strong intermolecular forces will be very attracted to one another. This attraction means more energy will be required to break bonds. A good example is H2S vs H2O. Water has hydrogen bonding with other water molecules and therefore has a much higher boiling point.

[Brooke Gushiken 1B]

Hi! Molecules with stronger intermolecular forces will have a higher boiling point because it'll be harder to break the bonds between them/require more energy to break the bonds. Therefore, the molecules with ion-dipole interactions will have the highest boiling point, then hydrogen bonds, dipole-dipole, and London dispersion forces (induced dipole-induced dipole).

[Crystal Ma 2J]

Stronger forces= higher boiling point!

[Shannon Lau 14B - 1H]

From strongest to least - highest boiling point to low:
ion-ion
ion-dipole
hydrogen bond
dipole-dipole
London dispersion forces

[Vashe Sundar 3H]

Hi!

The stronger the intermolecular force is, the harder and more energy is required to break intermolecular forces. The strength of intermolecular forces from strongest to weakest are: Ion-dipole > hydrogen bonding > dipole-dipole > London dispersion forces.

If the intermolecular forces are the same, then you should default to the molecular size and weight to determine the boiling point relative to other molecules.

[LukeYing_3H]

Stronger intermolecular forces will mean a higher boiling point as more energy is needed to break these intermolecular attractions. The strength of intermolecular forces from strongest to weakest are: Ion-dipole > hydrogen bonding > dipole-dipole > London dispersion forces.

[Brianna Mercado 3D]

hello! the stronger the force= the higher the melting point! Hope this helps

[Eric Sun 2G]

If a molecule has stronger IMF, the boiling point will be higher as it takes more energy to break the existing intermolecular forces in between each molecule.

[Alejandra Hernandez 2A]

Hi! Generally, the stronger the IMF is, the higher the boiling point will be. The order from strongest to weakest bond is ion-ion>ion-dipole>hydrogen bond>dipole-dipole> london dispersion forces; this would then also be the order from highest to lowest boiling point. Hope this helped :))

[Katryn Heine 3A]

Molecules with stronger IMF will typically have a higher boiling point. This is because is the IMF is stronger it'll require more energy to break the bonds in the molecule. One way to tell how strong a molecules IMF will be is by looking at its shape. Long chained molecules for example have stronger IMF than other molecules. The chain like structure makes it easier for IMF to form.

[Milli Zunich 3I]

The stronger the forces the higher the boiling point!

[405479701]

The stronger forces have higher boiling point. The weaker forces have lower boiling point.

[Sarah Hong 2K]

The stronger the intermolecular force the higher the melting point. For example ion-ion interaction will have a higher boiling point than hydrogen bonds. Hydrogen bonding will have a higher boiling point than dipole-dipole interactions which is stronger than London dispersion forces. The larger the atom is and the more electrons there are, the stronger the dispersion forces are and the higher the boiling point will be.

[daniellediem1k]

If the IMFs are stronger in a molecule, it will have a higher boiling point.

[Sarah Lesmeister 2F]

Stronger intermolecular forces means that it will have a higher boiling point because it's going to take more energy to break

[Maggie Clark]

High boiling point means higher intermolecular forces. So the order of strongest to weakest is: Hydrogen bond - Hydrogen bond, Dipole - Hydrogen bond, Dipole - Dipole, Dipole - Induced Dipole, Induced - Induced.

[SerenaSabedra]

A higher boiling point corresponds to stronger IM forces because those forces attract molecules to each other, thus requiring more energy to break these bonds. IM forces such as ion-dipole and hydrogen bonding are examples of forces that will lead to a higher boiling/melting point.

[Jordyn Lee 1J]

Hi, you can determine which molecule has a higher boiling point by identifying which intermolecular forces each molecule can have. Whichever molecule has the stronger intermolecular forces has the higher boiling point.

[Joan Moci 1J]

The molecule with the stronger imfs will have the higher boiling point as more energy will be required to overcome the intermolecular attraction. Generally, molecules that can undergo undergo hydrogen bonding will have higher boiling points than those that can undergo dipole-dipole and those will have higher than those that only have London dispersion forces. However the size and shape of the molecule can also be taken into account as a very large molecule that only has LDFs will have a higher boiling point than a smaller molecule because there are more e- that can be distorted.

[SofiaMammaro-1K]

The stronger the IMFs, the lower the vapor pressure of the substance and the higher the boiling point. The order of strengths of intermolecular forces is:
ion-ion > H-bonding > dipole-dipole > London dispersion
.

[Alyssa Cua 2J]

Hi Megan!
Molecules with stronger intermolecular forces will have higher boiling points because more energy is needed to “break” these forces.

[905701360]

Stronger forces have higher boiling points.

[Amy Huynh 1B]

You would have to know the relative strengths of the intermolecular forces. For example, if one compound only had LDFs but another had LDFs and H-bonds, then the latter compound would have a higher BP/MP because it would take more energy to break those bonds.

[Anubhav_Chandla1G]

Usually, stronger intermolecular forces will lead to a higher boiling point. An example of this is that a compound with just LDF forces will have a lower boiling point compared to a compound that has hydrogen bonding within its elements.

[ElizabethKarlin2E]

I think the stronger the intermolecular forces, the higher the boiling point, so you would find all of the intermolecular forces present in the molecules you're given and the strongest one has the highest boiling point

[205819952]

Molecules with stronger intermolecular forces have higher boiling temperatures because they stick together more. Because of this attraction, more energy will be required to break bonds.
