Flashcards covering the key vocabulary related to intermolecular forces and their properties as discussed in the lecture.

Intramolecular Forces

Forces that occur within a molecule, holding atoms together.

Intermolecular Forces

Forces that occur between molecules, influencing physical properties.

Ion-Dipole Force

An intermolecular force between an ion and a polar molecule.

Hydrogen Bonding

An extreme form of dipole-dipole interactions involving hydrogen and electronegative atoms.

Dipole-Dipole Interaction

Attraction between polar molecules due to permanent regions of polarity.

Dipole-Induced Dipole

Occurs when a polar molecule induces a dipole in a nonpolar molecule.

Induced Dipole-Induced Dipole (London Dispersion Forces)

Weak forces that result from temporary dipoles in molecules.

Polarizability

The degree to which an electron cloud can be distorted.

Boiling Point

The temperature at which a liquid turns into gas, influenced by intermolecular forces.

Solubility

The ability of a substance to mix with another substance, dependent on interactions.

Viscosity

The resistance of a liquid to flow; thicker liquids have higher viscosity.

Surface Tension

The force that causes liquid molecules to be pushed together at the surface.

Temporary Dipole

A short-lived dipole that occurs due to the movement of electrons.

Diffusion

The process of solute mixing with solvent; influenced by molecular interactions.

Functional Groups

Specific groups of atoms within molecules that determine chemical properties.
