Intermolecular Force

Each list begins with basic conceptual vocabulary you need to know for MCAT questions and proceeds to advanced terms that might appear in context in MCAT passages. The terms are links to Wikipedia articles.
Intermolecular force
An intermolecular force is a force that acts between stable molecules or between functional groups of macromolecules which are generally much weaker than the chemical bonding forces.
Hydrogen bond
A hydrogen bond is a special type of dipole-dipole interaction that exists between an electronegative atom and a hydrogen atom bonded to another electronegative atom.
Hydrophobicity refers to the physical property of a molecule that is repelled from a mass of water
Van der Waals force
The name van der Waals force is sometimes used as a synonym for the totality of non-covalent forces which act between stable molecules.
Water dimer
The water dimer consists of two water molecules loosely bound by a hydrogen bond. It is the smallest water cluster.
Noncovalent bond
A noncovalent bond is a type of chemical bond, typically between macromolecules, that does not involve the sharing of pairs of electrons, but rather involves more dispersed variations of electromagnetic interactions.
The debye (symbol: D) is a non-SI and non-CGS unit of electrical dipole moment.
Lennard-Jones potential
The Lennard-Jones potential is a simple mathematical model that represents the condition of neutral atoms and molecules being subject to an attractive force at long ranges and a repulsive force at short ranges.
