In one to two sentences, explain why structural formulas are a good option for depicting complex molecules such as carbon-based compounds and polymers.

Structural formulas are effective for depicting complex molecules because they provide a clear visual representation of the arrangement of atoms, bonds, and functional groups, which is crucial for understanding the molecule's chemical behavior and reactivity. This level of detail helps to convey structural information that is often lost in simpler formula representations, making it easier to analyze and communicate molecular composition.
