How are vaporization and intermolecular forces related?

Vaporization occurs when a liquid changes to a gas, which makes it an endothermic reaction. Water’s heat of vaporization is 41 kJ/mol. Vapor pressure is inversely related to intermolecular forces, so those with stronger intermolecular forces have a lower vapor pressure.

What is the relationship between viscosity and intermolecular forces?

Viscosity is the resistance of liquids to flow. Viscosity increases with 1) stronger intermolecular forces and 2) decreasing temperature. Surface tension results from the net inward force experienced by the molecules on the surface of a liquid. It causes water to “bead up” when in contact with nonpolar surfaces.

What’s the difference between intramolecular and intermolecular?

To start, let’s define intramolecular and intermolecular. ‘Intra’ means within, so intramolecular forces occur within a molecule. ‘Inter’ means between, so intermolecular forces occur between molecules. The difference can be seen in this image.

How are intermolecular forces and molecule size related?

Molecular Size Larger and heavier atoms and molecules exhibit stronger dispersion forces than smaller and lighter ones. In a larger atom or molecule, the valence electrons are, on average, farther from the nuclei than in a smaller atom or molecule. They are less tightly held and can more easily form temporary dipoles.

Which liquid has the strongest intermolecular force?

Water
Water has the strongest intermolecular forces (hydrogen bonds) of all the substances used.

What is the relationship between intermolecular forces and 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.

What are the 5 intermolecular forces 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 from weakest to strongest?

Intermolecular forces In the order of weakest to strongest:

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

Which liquid has the weakest intermolecular forces?

Oil- Only London Dispersion Forces (the weakest intermolecular force)
Water- London Dispersion, Dipole-Dipole, and Hydrogen Bonding.

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 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 examples of intermolecular forces?

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 an intramolecular force?

An intramolecular force is any force that binds together the atoms making up a molecule or compound, not to be confused with intermolecular forces, which are the forces present between molecules. The subtle difference in the name comes from the Latin roots of English with inter meaning between or among and intra meaning inside.
