Line-Angle Formula

A shorthand representation of organic molecules where lines represent bonds and vertices represent carbon atoms, simplifying structural depiction.

Resonance Structure

Different Lewis structures representing the same molecule that differ only in the positions of the electrons, not the positions of the atoms.

Organic Molecule

A molecule of the kind typically found in living systems, often containing carbon atoms bonded to hydrogen, oxygen, or nitrogen.

Resonance Forms

Different Lewis structures for a molecule that depict the same arrangement of atoms but differ in the distribution of electrons.
