FAQ
Frequently Asked Questions
No. A molecular formula (e.g., C6H12O6) only states the number and types of atoms. A structural formula shows how those atoms are bonded together.
It is a fundamental term in chemistry, especially organic chemistry, and also appears in biochemistry, pharmacology, and materials science.
A standard structural formula typically shows connectivity (constitution). To show 3D shape (stereochemistry), specific notations like wedges and dashes are added, creating a stereochemical formula.
A full structural formula shows every atom and every bond. A condensed structural formula groups atoms together (e.g., CH3CH2OH for ethanol) to save space while still implying connectivity.
A diagram that shows the arrangement of atoms within a molecule and the chemical bonds between them.
Structural formula is usually academic, technical, scientific in register.
Structural formula: in British English it is pronounced /ˈstrʌk.tʃər.əl ˈfɔː.mjʊ.lə/, and in American English it is pronounced /ˈstrʌk.tʃɚ.əl ˈfɔːr.mjə.lə/. Tap the audio buttons above to hear it.
