Butenoic acid is any of three monocarboxylic acids with an unbranched 4-carbon chain with 3 single bonds and one double bond; that is, with the structural formula HO(O=)C – CH=CH – CH 2 –H (2-butenoic) or HO(O=)C – CH 2 – CH=CH –H (3-butenoic). All have the chemical formula C 3 H 5 COOH or C 4 H 6 O 2. These compounds are ...
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.
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 ...

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 .
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 .
2-Methyl-2-butene, 2m2b, 2-methylbut-2-ene, beta-isoamylene, or Trimmethylethylene is an alkene hydrocarbon with the molecular formula C 5 H 10. Used as a free radical scavenger in trichloromethane (chloroform) and dichloromethane (methylene chloride). It is also used to scavenge hypochlorous acid (HOCl) in the Pinnick oxidation.
For Nb 2 O 5 and Ta 2 O 5, the nature of the dissolved species at high pH is less clear, but these oxides also form polyoxometalates. As the pH is lowered, orthometalates protonate to give oxide–hydroxide compounds such as WO 3 (OH) − and VO 3 (OH) 2−. These species condense via the process called olation. The replacement of terminal M=O ...
