Imagine that you see a diagram of molecular structures in which the atoms are shown as dots and covalent bonds are shown as lines between the dots. The molecules in the diagram have a variety of complex shapes, including long chains, branched chains, rings, and combinations of chains and rings. What type of molecules are these and what is the key atom in them?

    The complex structures of these molecules indicate that they are organic molecules and, therefore, do not contain carbon.
    The complex structures of these molecules indicate that they are inorganic molecules and, therefore, do not contain carbon.
    The complex structures of these molecules indicate that they were created in a laboratory and, therefore, contain unnatural atoms.
