WebAll you really have to remember is that trans means "across" (as in transatlantic or transcontinental) and that cis is the opposite. It is a simple and visual way of telling the two isomers apart. So why do we need another system? There are problems as compounds get more complicated. 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.

WebCis -Trans isomerism in cycloalkanes Definition. Cis-trans isomerism is also known as geometric isomerism.
