There are three different types of intermolecular forces in terms of strength. They are (strongest to weakest) hydrogen bonding, dipole-dipole and Van der Waals’ forces.
What are the three intermolecular forces from strongest to weakest?
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.
What are the 3 intermolecular forces?
There are three types of intermolecular forces: London dispersion forces (LDF), dipole- dipole interactions, and hydrogen bonding.
What is the strongest and weakest intermolecular forces?
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 type of intermolecular force is the weakest?
London dispersion forces, under the category of van der Waal forces: These are the weakest of the intermolecular forces and exist between all types of molecules, whether ionic or covalent—polar or nonpolar.
Which hydrogen bonding is the strongest?
The strength of hydrogen bond depends upon the coulumbic interaction between the electronegativity of the attached atom and hydrogen. Fluorine is the most electronegative element. F−H−−−F bond will be strongest H bond.
What is the strongest intermolecular force in water?
The strongest intermolecular force in water is a special dipole bond called the hydrogen bond. Many molecules are polar and can form bipole-bipole bonds without forming hydrogen bonds or even having hydrogen in their molecule.
How do you know which intermolecular force is stronger?
5. Bottom Line
- Boiling points are a measure of intermolecular forces.
- The intermolecular forces increase with increasing polarization of bonds.
- The strength of intermolecular forces (and therefore impact on boiling points) is ionic > hydrogen bonding > dipole dipole > dispersion.

How can you tell the difference between intermolecular forces?
In any case you have H – F for example, and another H – F. And so in between the H and the F you would have an intermolecular force. And intermolecular force between those molecules would be Hydrogen bonding. So you have a Hydrogen bond over there.
Why hydrogen bonding is the strongest intermolecular force?
Hydrogen bonds are strong intermolecular forces created when a hydrogen atom bonded to an electronegative atom approaches a nearby electronegative atom. Greater electronegativity of the hydrogen bond acceptor will lead to an increase in hydrogen-bond strength.
What is the weakest force in chemistry?
The London dispersion force is the weakest intermolecular force. The London dispersion force is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles. This force is sometimes called an induced dipole-induced dipole attraction.
Which state of matter has the least intermolecular forces?
The state of matter with the least intermolecular forces of attraction is the gaseous state. The molecules of gases are loosely bounded and are far apart from each other.
What is the weakest molecular attraction?
The weakest intermolecular force is the London force of dispersion. The London dispersion force is a temporary attractive force which results when the electrons occupy positions that make the atoms form temporary dipoles in two adjacent atoms.
Which bonds are the strongest and weakest?
Thus, we will think of these bonds in the following order (strongest to weakest): Covalent, Ionic, Hydrogen, and van der Waals.
What is the strongest intermolecular force present in carbon monoxide?
The dipole-dipole attractions between CO molecules are comparably stronger than the dispersion forces between nonpolar N2 molecules, so CO is expected to have the higher boiling point.
What has the strongest intermolecular forces solid liquid or gas?
Yes, intermolecular forces are the strongest in solids. “In solids, the intermolecular forces are very strong, and the constituent particles are closely packed. That is why; solids are incompressible and have high density.
