As you would expect, the strength of intermolecular hydrogen bonding and dipole-dipole interactions is reflected in higher boiling points.
What bonds have the highest boiling point?
Hydrogen bonding is an extreme type of dipole-dipole bonding. These forces are weaker than intramolecular bonds, but are much stronger than other intermolecular forces, causing these compounds to have high boiling points.
Does higher intermolecular forces affect boiling point?
Higher the intermolecular forces between the liquid particles, harder it is for it to escape into the vapor phase, ie., you need more energy to convert it from liquid to the vapor phase, in other words, higher its boiling point.
How do you know which molecule has a higher boiling point?
There are 3 important trends to consider.
- The relative strength of the four intermolecular forces is: Ionic > Hydrogen bonding > dipole dipole > Van der Waals dispersion forces. …
- Boiling points increase as the number of carbons is increased.
- Branching decreases boiling point.

What type of intermolecular force contributes to the high boiling point of water?
High boiling point and low melting point. Water has strong hydrogen bonds between molecules. These bonds require a lot of energy before they will break. This leads to water having a higher boiling point than if there were only weaker dipole-dipole forces.
Which attractive force is the weakest?
Dispersion forces are the weakest intermolecular force (one hundredth-one thousandth the strength of a covalent bond), hydrogen bonds are the strongest intermolecular force (about one-tenth the strength of a covalent bond).
What are the strongest to weakest intermolecular forces?
In order from strongest to weakest, the intermolecular forces given in the answer choices are: ion-dipole, hydrogen bonding, dipole-dipole, and Van der Waals forces.
Which intermolecular force is the strongest?
Dipole-dipole interactions are the strongest intermolecular force of attraction.
What increases boiling point?
Boiling points are a measure of intermolecular forces. The intermolecular forces increase with increasing polarization of bonds. Boiling point increases with molecular weight, and with surface area.
Which substance has the highest melting and boiling points?
The chemical element with the highest melting point is tungsten, at 3,414 °C (6,177 °F; 3,687 K); this property makes tungsten excellent for use as electrical filaments in incandescent lamps.
What can affect boiling point?
The similarity between melting points and boiling points means that the same factors that impact the melting point of a compound will also impact the boiling point. Therefore, the strength and types of intermolecular forces that are found within the liquid compound will affect the boiling point.
What liquid has the highest boiling point?
Explanation: Acetone 56.0 ∘C .
Which solution has the highest boiling point?
Thus, Na3PO4 has the highest boiling point.
Which intermolecular force is responsible for the high boiling point of H2O?
Hydrogen bonding, a particularly strong dipole-dipole force, causes a powerful attraction between water molecules, which results in a high boiling point.
Which intermolecular force would affect the boiling point the least answers com?
Dispersion forces would have the least effect on the boiling point of a liquid. They are the weakest intermolecular forces.
Which compound has the strongest hydrogen bonding between its molecules?
The higher the electronegativity the stronger the attraction that the halogen attracts the electrons and the stronger the hydorgen bonding. Then, the conclusion is that HF has the strongest hydrogen bonding.
