The isomeric forms are 1-butene, cis - 2-butene, trans -2-butene, and isobutylene. [citation needed] Most commercially available butane also contains a certain amount of contaminant oil which can be removed through filtration but which will otherwise leave a deposit at the point of ignition and may eventually block the uniform flow of gas. The '-ene' refers to an alkene, so we know that butene's structure must include a carbon double bond. Of butane the molecular formula is C4H10. The chemical formula for butene is: C4 H8, which means it's made up of four carbon atoms and eight hydrogen atoms. According to IUPAC nomenclature, these isomers are called simply butane and 2-methylpropane.
