Structural formula

A structural formula is a way chemists represent molecules by showing how atoms are connected and arranged. Unlike simple chemical formulas that just list the types and numbers of atoms (like CH₄ for methane), a structural formula reveals the specific bonds between atoms and their arrangement in space. This helps to understand the molecular shape, bonding, and reactivity. It uses lines to depict bonds—single, double, or triple—between atoms, providing a clear picture of the molecule’s structure, which is essential for studying chemical behavior and properties.
