Question

In 2-3 sentences, answer this question. What is a structural formula, and how does it differ from a molecular formula? Please make your answer simple, coherent, and intended for 9th grade.

Answer 1

A structural formula shows how atoms are connected in a molecule, displaying the arrangement of bonds between them. In contrast, a molecular formula simply lists the types and numbers of atoms in a molecule without revealing their connections or structure. For example, the molecular formula for water is H₂O, while its structural formula shows the bonds between one oxygen atom and two hydrogen atoms.
