Question

The attractive forces between polar molecules are known as ________ forces and between non-polar molecules are known as ______ forces.

• A. Dipole-dipole, London dispersion
• B. Dipole-induced dipole, London dispersion
• C. London dispersion, Dipole-dipole
• D. Ion-dipole, Dipole-dipole

Answer 1

The correct option is A Dipole-dipole, London dispersion

The intermolecular attractive forces between two polar molecules would be dipole-dipole interactions.
London dispersion force is a temporary attractive force that results when the electron cloud in two adjacent atoms/molecules occupy positions that make the atoms/molecules form momentary dipoles. London forces are the attractive forces between non-polar molecules.
