Web1-Pentene is an alpha-olefin. Most often, 1-pentene is made as a byproduct of catalytic or thermal cracking of petroleum, or during production of ethylene and propylene via thermal cracking of hydrocarbon fractions. The only commercial manufacturer of 1-pentene is Sasol Ltd, where it is separated from crude made by the Fischer–Tropsch process. WebThe cis isomer is more stable than the trans isomer by approximately 40 kJ mole − 1. With an increasing number of CH₂ groups to span the two carbon atoms of the double bond, the strain of the trans isomer becomes less severe. For example, the isomeric cyclododecenes are of comparable stability. Sign in to download full-size image Problem 5.8
