Z2butene
Z2butene, also written as Z-2-butene or cis-2-butene, is an alkene with the formula C4H8 and is the cis isomer of but-2-ene. The Z designation indicates that the two higher-priority substituents (the methyl groups) lie on the same side of the carbon–carbon double bond.
Structure and nomenclature: The molecule has a CH3-CH=CH-CH3 backbone with the two methyl groups on the same
Physical properties: Z-2-butene is typically a colorless, flammable gas or low-boiling liquid at room temperature, with
Production and occurrence: It is produced in petrochemical processes and occurs in various fractions of crude
Reactions: As a simple alkene, cis-2-butene participates in standard addition reactions. Bromine addition gives 2,3-dibromobutane, with
Applications and significance: Z-2-butene serves as a chemical building block and reference compound in stereochemistry studies.
Safety: It is flammable and can be irritating if inhaled or contacted with skin or eyes. Proper
