Cis2undecene

Cis-2-undecene is an organic compound with the chemical formula C11H22. It is an alkene, meaning it contains a carbon-carbon double bond. In cis-2-undecene, the double bond is located between the second and third carbon atoms of an eleven-carbon chain. The "cis" designation indicates that the hydrogen atoms attached to the carbon atoms involved in the double bond are on the same side of the double bond. This geometric isomerism distinguishes it from its trans counterpart, trans-2-undecene, where the hydrogen atoms are on opposite sides.

This compound is a colorless liquid at room temperature and pressure. Like other alkenes, it is relatively nonpolar and insoluble in water but soluble in organic solvents. Cis-2-undecene can be synthesized through various organic chemistry reactions, often involving the reduction of alkynes or the elimination of halogens from haloalkanes. It can also be formed as a component in mixtures of isomeric undecenes produced from petrochemical processes.

While cis-2-undecene itself may not have widespread direct industrial applications, it serves as a model compound in academic research related to alkene chemistry, catalysis, and organic synthesis. Its specific stereochemistry can influence its reactivity in addition reactions and polymerization processes. It is also a minor component found in some natural products and fragrance compounds, contributing to their overall scent profile.
