12pentadiene

12-Pentadiene is an organic compound with the chemical formula C7H12. It is an alkadiene, a type of hydrocarbon that contains two carbon-carbon double bonds. The molecule consists of a pentane chain with two double bonds, one located between the second and third carbon atoms and the other between the fifth and sixth carbon atoms. This arrangement gives 12-pentadiene a linear structure with alternating single and double bonds.

The compound is a colorless liquid at room temperature and has a characteristic odor. It is highly reactive due to the presence of the double bonds, which can participate in addition reactions. 12-Pentadiene is used as a precursor in the synthesis of various chemicals, including polymers and pharmaceuticals. Its reactivity makes it a valuable intermediate in organic synthesis.

In terms of physical properties, 12-pentadiene has a boiling point of approximately 110°C and a melting point of around -100°C. It is soluble in organic solvents but insoluble in water. The molecule's structure allows for cis and trans isomers, which have different physical and chemical properties.

12-Pentadiene can be prepared through various methods, including the dehydration of alcohols and the dehydration of alkenes. It can also be synthesized through the reaction of acetylenes with alkenes in the presence of a catalyst. The compound is typically handled with care due to its reactivity and potential hazards associated with its handling and storage.
