Hence, organic chemists developed several methods for illustrating or jotting down molecular structures. Some compounds can form repeating sub-units of atoms or molecules in one large complex chain, which is especially true for organic compounds. A condensed structural formula may also be referred to as a semi-structural formula. We could name it 2-butene, but there are actually two such compounds; the double bond results in cis-trans isomerism (Figure \(\PageIndex{3}\)).
