"Alkadienes have been under study for a long time, until the last decade of the 19th century, various structures have been known, each structure represents the specific chemical properties of the compound, alkadienes structures are the first important step for better identification of these compounds, by identifying the structures, different types of alkadienes can be distinguished from each other. Also, the structures of alkadienes and important synthetic compounds are of great value in industry and medicine. Conjugated, isolated, and cumulated structures have been identified by different people at different times in alkadienes. Compounds of alkadienes i.e. conjugated, isolated and cumulated alkadienes have chain and cyclic structures, alkadienes are used as medicine to treat some deadly diseases, for example Taxol in 1960, Jonathan Hartwell in the United States collected some plants such as pacific yew for the treatment of breast cancer. Also, in the 19th century, synthetic and natural polymers of alkadienes were widely used in the tire industry, in general, alkadienes are compounds that have two carbon-carbon double bonds (π) in their composition, that is why they are very active compounds, it is widely used in industry all over the world and they have caused the development of the world’s economy and industry.
