What does a structural formula show?

• A. Shows how the atoms are bonded
• B. Shows the mass of the molecule
• C. Shows the isotopic composition
• D. Shows only the empirical ratio

Answer: (A)

A structural formula shows how the atoms are bonded to each other and arranged in the molecule. The lines represent bonds—single, double, or triple—so you can see which atoms connect to which and how the carbon framework or main skeleton is built. This connectivity also highlights functional groups and the overall shape that governs properties and reactivity. It doesn’t provide the mass of the molecule (that comes from summing atomic masses), and isotopic composition isn’t shown unless you explicitly label isotopes. It also isn’t just an empirical ratio, which would omit how atoms are actually connected. So the structural formula is about bonds and arrangement, not just what the molecule is made of in simple counts or its weight.
