They are traditionally called cis-2-butene and trans-2-butene or, in slightly … The first psico-oxetanocin analogue of the powerful antiviral natural product, oxetanocin A, has been readily synthesized from cis-2-butene-1,4-diol. Its main uses are in the production of gasoline (petrol) and butadiene, although some 2-butene is also used to produce the solvent butanone. This section and the following one illustrate some idiosyncrasies that happen when you try to compare the two systems. The second isomer for butene is cis-2-butene or cis-beta-butylene. Stereoisomers: 2-Butene, (E)-. It is the simplest alkene exhibiting cis/trans-isomerism (also known as (E/Z)-isomerism); that is, it exists as two geometric isomers cis-but-2-ene ((Z)-but-2-ene) and trans-but-2-ene ((E)-but-2-ene). However, stereoisomers crop up in many of the other structural types of organic chemistry. 2-ブテン(2-Butene)は、炭素数4のアルケンである。 幾何異性体を持つ最も単純なアルケンであり、cis-2-ブテン((Z)-2-ブテン)とtrans-2-ブテン((E)-2-ブテン)の2つの形が存在する。. Copy Sheet of paper on top of another sheet.54 ± 0. Therefore, there are two different ways to construct the 2-butene molecule. Let's analyze them to see whether they are E or Z.3. It is a petrochemical, produced by the catalytic cracking of crude oil or the dimerization of ethylene. Hope that helps. 2-Butene occurs in coal gas and has been detected in diesel exhaust.
