structural formula
Quick Summary
A structural formula in chemistry is a type of expression that shows the arrangement of atoms and the bonds between them within a molecule. Unlike a molecular formula, which only lists the types and numbers of atoms, a structural formula reveals how these atoms are connected.123
Structural formulas use symbols for elements and lines to represent chemical bonds. A single line indicates a single bond, two lines a double bond, and three lines a triple bond. This detailed representation is crucial for understanding how compounds with the same atoms can have different properties due to varying atomic arrangements. Carbon's unique ability to form extensive networks of covalent bonds with itself and other elements leads to a vast diversity of organic compounds, all of which can be represented using structural formulas.23
