... Now, not only is it possible to generate ethyl six molecules. In the previous aromatic ring system we have six carbons, attached to the metal atom. In this case, you have seven carbon atoms attached to the metal. You will notice that, C seven H eight is a cyclic molecule, which is not conjugated to ...
