What are Intermolecular Forces (IMFs)?

Back

Intermolecular Forces (IMFs) are forces of attraction or repulsion between neighboring particles (molecules, atoms, or ions). They play a crucial role in determining the physical properties of substances.

Front

What is the strongest type of intermolecular force?

Back

Ionic bonding is considered the strongest type of intermolecular force.

Front

What is London Dispersion Force?

Back

London Dispersion Forces are weak intermolecular forces that arise from temporary dipoles in atoms and molecules. They occur in all atoms and molecules.

Front

What is dipole-dipole attraction?

Back

Dipole-dipole attraction is the interaction between two permanent dipoles, typically found in polar molecules.

Front

How do intermolecular forces affect boiling points?

Back

As intermolecular forces increase, the boiling point of a substance also increases due to the greater energy required to overcome these forces.

Front

What is hydrogen bonding?

Back

Hydrogen bonding is a strong type of dipole-dipole attraction that occurs when hydrogen is bonded to highly electronegative atoms like nitrogen, oxygen, or fluorine.

Front

What is the relationship between vapor pressure and intermolecular forces?

Back

As intermolecular forces increase, vapor pressure decreases because fewer molecules can escape into the gas phase.

Front

What is the significance of solubility in relation to IMFs?

Back

Solubility is influenced by intermolecular forces; substances with similar types of IMFs tend to be soluble in each other (like dissolves like).

Front

What is a polar molecule?

Back

A polar molecule is a molecule that has a net dipole moment due to the presence of polar bonds, resulting in a positive and negative end.

Front

What is a nonpolar molecule?

Back

A nonpolar molecule is a molecule that does not have a net dipole moment, often due to symmetrical distribution of charge.
