Intermolecular Interactions Lecture Notes

A set of flashcards detailing key vocabulary and concepts related to intermolecular interactions.

Atom

The basic unit of a chemical element, consisting of protons, neutrons, and electrons.

Ionic Bond

A type of bond formed through the electrostatic attraction between oppositely charged ions.

Covalent Bond

A chemical bond formed when two atoms share one or more pairs of electrons.

Electronegativity

The measure of an atom's ability to attract and hold onto electrons.

Hydrogen Bond

A strong type of dipole-dipole interaction that occurs between molecules with hydrogen attached to electronegative atoms.

Van der Waals Forces

Weak intermolecular forces that arise from temporary shifts in electron density.

Ion-Dipole Interaction

An attraction between an ion and a polar molecule.

Dipole-Dipole Interaction

An attraction between the positive end of one polar molecule and the negative end of another.

Covalent Bonding Example

Aspirin irreversibly blocks COX enzymes through the acetylation of serine.

Ionic Bonding Example

Alginates form ionic bonds with divalent cations in the stomach to create gel rafts.

Colestyramine

An ionic exchange resin that forms complexes with bile acids and is excreted in feces.

London Dispersion Forces

Weak intermolecular forces that occur due to temporary changes in electron density in atoms or molecules.

Salt Formation

A process that increases the water solubility of drugs through ion-dipole interactions.
