Introduction to Reactivity and Resonance Structures

A set of vocabulary flashcards covering key terms and concepts in chemistry related to the ozone layer, CFCs, resonance structures, and molecular geometry.

Ozone Layer

A region of Earth's stratosphere that absorbs most of the sun's harmful ultraviolet radiation, primarily composed of ozone (O3) gas.

CFCs

Chlorofluorocarbons, chemical compounds used in aerosols and refrigerants; harmful to the ozone layer as they break apart under UV light.

Montreal Protocol

An international treaty designed to phase out the production and consumption of substances responsible for ozone depletion.

Resonance Structure

Different ways of drawing the same molecule that represent the delocalization of electrons within the molecule.

Free Radical

A molecule with an unpaired electron, making it highly reactive and able to combine with other molecules.

VSEPR Theory

Valence Shell Electron Pair Repulsion theory, which predicts the shape of molecules based on the repulsion between electron pairs.

Paramagnetic Molecule

A molecule that has unpaired electrons and is attracted to magnetic fields.

Bond Length

The distance between the nuclei of two bonded atoms, which can vary depending on the type of bond.

Lewis Structure

A representation of a molecule that shows how the atoms are bonded and the arrangement of electrons.

Electron Domain

The region around a central atom in a molecule where electrons are likely to be found, influencing molecular shape.
