cis-2-Pentene

Description:
Cis-2-pentene is an organic compound classified as an alkene, specifically an isomer of pentene. Its molecular formula is C5H10, indicating it contains five carbon atoms and ten hydrogen atoms. The "cis" designation refers to the configuration of the double bond between the second and third carbon atoms, where the substituents are on the same side, resulting in a bent structure that influences its physical properties. Cis-2-pentene is a colorless liquid at room temperature and has a characteristic odor. It is less dense than water and is insoluble in water but soluble in organic solvents. The compound is flammable and can participate in various chemical reactions typical of alkenes, such as hydrogenation, polymerization, and electrophilic addition. Its boiling point and melting point are influenced by the presence of the double bond and the molecular structure. Cis-2-pentene is used in organic synthesis and as an intermediate in the production of various chemicals, including plastics and other materials. Safety precautions should be taken when handling this compound due to its flammable nature.
