2Heptadecene

2-Heptadecene is an organic compound with the chemical formula C17H34. It is an alkene, meaning it contains a carbon-carbon double bond. Specifically, the double bond is located between the second and third carbon atoms of the seventeen-carbon chain. Its isomer, 1-heptadecene, has the double bond at the terminal position. 2-Heptadecene exists as cis and trans isomers due to the restricted rotation around the double bond. The cis isomer has the hydrogen atoms on the same side of the double bond, while the trans isomer has them on opposite sides.

This compound can be synthesized through various organic reactions, such as the Wittig reaction or the dehydration of 2-heptadecanol. It is a relatively nonpolar molecule and is insoluble in water but soluble in organic solvents like ethanol and ether. Its physical properties, such as boiling point and melting point, are dependent on whether it is the cis or trans isomer.

2-Heptadecene can undergo typical alkene reactions, including addition reactions across the double bond, such as hydrogenation, halogenation, and hydrohalogenation. These reactions can lead to the formation of saturated hydrocarbons or halogenated alkanes. While not a widely produced industrial chemical, it may be found as a component in certain natural products or as an intermediate in specialized chemical syntheses. Its presence in biological systems is less common compared to shorter or longer chain alkenes.
