INTERMOLECULAR FORCES

Front

What are intermolecular forces?

Back

Intermolecular forces are the forces of attraction or repulsion between neighboring particles (molecules, atoms, or ions). They are responsible for the physical properties of substances, such as boiling and melting points.

Front

What is the strongest type of intermolecular force?

Back

The strongest type of intermolecular force is ionic bonding.

Front

What is the second strongest intermolecular force after hydrogen bonding?

Back

The second strongest intermolecular force is dipole-dipole attraction.

Front

What type of intermolecular force is present in water?

Back

Water exhibits strong hydrogen bonding due to the presence of highly polar O-H bonds.

Front

What explains the high boiling point of water?

Back

The high boiling point of water is explained by the strong hydrogen bonds between water molecules.

Front

Does HCl exhibit hydrogen bonding?

Back

No, HCl does not exhibit hydrogen bonding because it does not have a hydrogen atom bonded to a highly electronegative atom like oxygen, nitrogen, or fluorine.

Front

Does CH4 exhibit hydrogen bonding?

Back

No, CH4 (methane) does not exhibit hydrogen bonding because it does not have a highly electronegative atom bonded to hydrogen.

Front

What is dipole-dipole attraction?

Back

Dipole-dipole attraction is an intermolecular force that occurs between polar molecules, where the positive end of one molecule is attracted to the negative end of another.

Front

What is the role of London dispersion forces?

Back

London dispersion forces are weak intermolecular forces that arise from temporary dipoles in molecules, present in all substances, but are the only forces in nonpolar molecules.

Front

How do intermolecular forces affect boiling points?

Back

Stronger intermolecular forces result in higher boiling points, as more energy is required to overcome these forces during the phase change from liquid to gas.
