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 are London dispersion forces?

Back

London dispersion forces are weak intermolecular forces that occur between nonpolar molecules due to temporary dipoles that occur when electron distribution is uneven.

Front

What types of molecules experience London dispersion forces?

Back

London dispersion forces occur between nonpolar molecules.

Front

What are dipole-dipole forces?

Back

Dipole-dipole forces are attractive forces between the positive end of one polar molecule and the negative end of another polar molecule.

Front

What types of molecules experience dipole-dipole forces?

Back

Dipole-dipole forces occur between polar molecules.

Front

What is hydrogen bonding?

Back

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

Front

Which intermolecular force is the strongest?

Back

Hydrogen bonding is generally considered the strongest type of intermolecular force.

Front

What are intramolecular forces?

Back

Intramolecular forces are the forces that hold the atoms within a molecule together, such as covalent or ionic bonds.

Front

How do intermolecular forces affect boiling and melting points?

Back

Stronger intermolecular forces result in higher boiling and melting points, as more energy is required to overcome these forces.

Front

What is the relationship between molecular size and London dispersion forces?

Back

As molecular size increases, London dispersion forces also increase due to a larger electron cloud, leading to stronger temporary dipoles.
