To unlock this lesson you must be a Study.com Member. Let's take a second to get into this. We will also learn how the structures affect the boiling point. Beilstein/REAXYS Number 505980 . We know it has four carbon atoms from the ''but'' portion of the name which means four. Other organic compounds have the formula C4H8, namely cyclobutane and methylcyclopropane, but are not alkenes and do not fall under the name butene. This makes it harder for it to boil, so the boiling point needs to be higher than with trans. It occurs as a colorless gas. - Structure, Synthesis & Derivatives, What is Hydroxyquinoline? - Structure & Derivatives, What is Trinitrotoluene?

They are traditionally called cis-2-butene and trans-2-butene or, in slightly more modern terms, (Z)- and (E)-2-butene.The Z and E stand for the German words for “together” (zusammen) and “apart” (entgegen).In principle, cis- and trans-2-butene are conformational isomers; in theory, they could… Butene, also called Butylene, any of four isomeric compounds belonging to the series of olefinic hydrocarbons. Molecular Weight 56.11 . The chemical formula of butene is C4 H8 and is an alkene, meaning it has a double bond somewhere in the molecule. Create an account to start this course today. Butene has a variety of uses, from the fuel in your car to the grocery bags you carry home! Cracking produces a mixture of products, and the butene is extracted from this by fractional distillation.[1]. The isomeric forms are 1-butene, cis - 2-butene, trans -2-butene, and isobutylene. 4088-60-2 [RN] But-2-en-1-ol, 1-Hy droxybut-2-ene. This relationship is called cis-trans isomerism.
