What simple compound and complex?

Answer 1

A simple compound consists of two or more elements chemically bonded together in a fixed ratio, such as water (H₂O) or carbon dioxide (CO₂). In contrast, a complex compound typically contains multiple types of atoms and may include various functional groups, often with more intricate structures, like glucose (C₆H₁₂O₆) or proteins. While simple compounds can be straightforward in composition, complex compounds exhibit greater diversity and complexity in their molecular architecture.
