Question
Question: Write the complete structural formula. 
Solution
We can see that the given structure of the organic compound is made up of four carbons and six hydrogen atoms. Because of the reason it is made up of only hydrogen and carbons , it is known as hydrocarbon. It has two double bonds so it is an alkene.
Complete step by step solution:
As we know that the IUPACnomenclature of the organic compound is 1,3−butadiene. It has four carbons and six hydrogen. The molecular formula of the given formula is CH2CHCHCH2. It can be written as C4H6. The structural formula of 1,3−butadiene can be represented as the given figure.

Additional information:
We know that the molecular mass of CH2CHCHCH2is (12×4)+(1×6)=54g/mol. CH2CHCHCH2 is an important organic compound produced in the process of petroleum. The majority of the CH2CHCHCH2 produced in the world is used to manufacture synthetic rubber. It is a colorless gas that can be easily condensed to liquid. According to studies and research it is found and proved that 1,3−butadiene can cause cancer to human beings. So it is said to be human carcinogen. It can cause cancer in the stomach, blood and lymphatic system. It is soluble in water and alcohol. The density of 1,3−butadiene is 615Kg/m3.
Note: Always remember that when an organic compound is made up of only carbons and hydrogens atoms then it is said to be a hydrocarbon. The IUPAC nomenclature of CH2CHCHCH2 is 1,3−butadiene. It has a mild gasoline odor. It is used to make tires, resins and plastics. It can cause cancer in human beings. The boiling point of the organic compound 1,3−butadiene is −4.4∘C.1,3−butadiene is made by the union of two vinyl groups.
