What are the 5 properties affected by intermolecular forces?

The physical properties of melting point, boiling point, vapor pressure, evaporation, viscosity, surface tension, and solubility are related to the strength of attractive forces between molecules. These attractive forces are called Intermolecular Forces.

What properties do molecules with stronger intermolecular forces have?

Molecules with stronger intermolecular force have higher melting points, boiling points, and viscosity. They have lower vapour pressures and evaporation rates. The intermolecular attractions hold the particles of a solid in position.

How does intermolecular forces affect properties?

Intermolecular forces are the forces that bind two molecules together. Physical properties are affected by the strength of intermolecular forces. Melting, boiling, and freezing points increase as intermolecular forces increase. Vapor pressure decreases as intermolecular forces increase.

Which attractive force is the weakest?

London dispersion force
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.

What is the weakest to strongest intermolecular force?

Intermolecular forces In the order of weakest to strongest:

  • dispersion force.
  • Dipole-dipole force.
  • Hydrogen bond.
  • Ion-dipole force.

What are the 3 intermolecular forces from weakest to strongest?

Which is the strongest intermolecular force below?

Explanation: Ion-dipole forces are the strongest of the intermolecular forces. Hydrogen bonding is a specific term for a particularly strong dipole-dipole interaction between a hydrogen atom and a very electronegative atom (oxygen, fluorine, or nitrogen).

What is the strongest intermolecular force?

hydrogen bonding Hydrogen Bonds is the strongest of all the intermolecular forces. The strongest attractive force is that created by the random movement of electron clouds – they are referred to by several names i) van der waals, ii) London (dispersion) forc…es, iii) instantaneous induced dipoles.

What are the three types of intermolecular forces?

The strength or weakness of intermolecular forces determines the state of matter of a substance (e.g., solid, liquid, gas) and some of the chemical properties (e.g., melting point, structure). There are three major types of intermolecular forces: London dispersion force, dipole-dipole interaction, and ion-dipole interaction.

What are some examples of intermolecular forces?

Intermolecular forces act between molecules. In contrast, intramolecular forces act within molecules. Intermolecular forces are weaker than intramolecular forces. Examples of intermolecular forces include the London dispersion force, dipole-dipole interation, ion-dipole interaction, and van der Waals forces.

What is the strength 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. Boiling point increases with molecular weight, and with surface area.
