But-2-ene is an acyclic alkene with four carbon atoms. 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). It is a petrochemical, produced by the catalytic cracking of crude oil or the dimerization ...

Isobutylene (or 2-methylpropene) is a hydrocarbon with the chemical formula (CH 3) 2 C=CH 2. It is a four-carbon branched alkene (olefin), one of the four isomers of butylene . It is a colorless flammable gas, and is of considerable industrial value.
[2] [3] [4] Acyclic alkenes, with only one double bond and no other functional groups (also known as mono-enes) form a homologous series of hydrocarbons with the general formula C n H 2n with n being a >1 natural number (which is two hydrogens less than the corresponding alkane).
In the chemical structures above, the small blue numbers in the structure images are the numbering of the atoms in the main backbone chain of the molecules. Other organic compounds have the formula C 4 H 8 , namely cyclobutane and methylcyclopropane , but are not alkenes and do not fall under the name butene .
Isomers with the molecular formula C 5 H 10 with CAS numbers C 5 H 10 is the molecular formula of 13 hydrocarbon isomers (represented by their CAS numbers on the chart). They can be divided into cycloalkanes and alkenes .
2,3-Epoxybutane is an organic compound with the formula CH 3 CH(O)CHCH 3. It is an epoxide . The compound exists as three stereoisomers , a pair of enantiomers and the meso isomer .
For example, 2-butene exists in two isomeric forms: cis-2-butene and trans-2-butene. [2] The sub-categories of isomerases containing racemases, epimerases and cis-trans isomers are examples of enzymes catalyzing the interconversion of stereoisomers.
