Intermolecular Forces

What is the strongest type of intermolecular force?

• London dispersion forces

• dipole-dipole forces

• ion-dipole forces

• hydrogen bonding forces

Who was the first to discover the intermolecular forces?

• Jacqueline E. van der Waals

• Jacobus van der Waals

• Johannes Diderik van der Waals jr.

• Johannes Diderik van der Waals

Which among the following are van Deer Waals' forces?

• Debye Forces

• Friction Forces

• Intramolecular Forces

• Tension Forces

How do you know if the molecule is considered "polar"?

• if there is an electronegativity difference between the bonded atoms

• if there is an electronegativity similarity between the bonded atoms

• if there is electronegativity equality between the bonded atoms

• if there is an electronegativity tension between the bonded atoms

It is the force that holds atoms together within a molecule.

• interomolecular forces

• intermolecular forces

• intramolecuilar forces

• intramolecular forces

What is the weakest type of intermolecular force?

• ion-dipole forces

• London Dispersion Forces

• hydrogen bonding forces

• Dipole-Dipole Forces

It is the attractive or repulsive force between molecules, between ions, or between molecules and ions.

• intarmolecular forces

• intermolecular forces

• intermecular forces

• intramolecular forces

For a force to be classified as hydrogen bonding, it must be a bond between hydrogen and 3 other high electronegative elements. Name all of them (you must type the element) (from the most electronegative element to 3rd most).

Molecules that have weaker intermolecular force will have _________ freezing point.

The stronger the intermolecular force, the _____ vapor pressures than molecules with weaker IMFs.
