AP Chemistry Unit 3 Vocab

Intermolecular Force

Interaction BETWEEN two different molecules

Intramolecular Force

Interaction within a single molecule

Dipole Dipole Interactions

Occur between any two polar molecules

Can be attractive or repulsive

Molecules orient themselves to maximize attraction

Hydrogen bonding

A very strong type of dipole dipole interaction where Hydrogen bonds with either Fluorine, Oxygen, or Nitrogen

London Dispersion Forces

Occur in all substances, caused by motion of electrons in an atom/molecule, causes it to have momentary dipole due to a negative charge in one place and a positive in another temporarily giving it a charge. A short occurrence and a weak force.

Polarizability

The ability of an atom to form a temporary or induced dipole

Induced Dipole

When a momentary dipole causes the neighboring species electrons to move—electrostatically attracted

**Make Flashcards of types of solids and their properties

Dipole

a pair of opposite partial charges (δ⁺ and δ⁻) separated by a distance.

High temp and Low pressure are closer to ideal gas law
