cis-but-2-eneNew low-energy electron scattering and vacuum UV absorption spectra for cis- and trans-but-2-enes have been interpreted by ab initio configuration interaction calculations, to yield a consistent in
To determine which statement is incorrect for cis-but-2-ene relative to trans-but-2-ene, we need to analyze the properties of both isomers based on their molecular structure and how this affects their physical properties.1. Identify the

Isobutene, cis- and trans-but-2-ene decrease the initial rate of ethanal pyrolysis. These inhibiting effects can be quantitatively interpreted by a kinetic scheme which appears as a new particular limiting case of a general inhibition or acceleration mechanism proposed and analyzed in 1966. The ...

and -but-2-ene oxides undergo SN2 opening with the lithium enolate derived from [(η5-C5H5)Fe(CO)(PPh3)COCH2CH3] in the presence of BF3·OEt2; preferential opening occurs where the enolate configuration at iron matches that of the epoxide carbon being attacked....
Cis/trans-but-2-enedioic acid estersAntimicrobial activity assayDFT studiesTime-kill assaySix novel cis/trans-but-2-enedioic acid esters had been synthesized to discover the new bioactive molecules that could kill food-related bacteria and fungi. Their structures were analyzed by melting point, LC...
The porous Vycor glass was photocatalytically active only for the cis-trans isomerization of cis-but-2-ene, which proceeds through a radical intermediate of the butene produced on the Lewis acid sites of silica-alumina frameworks or their dealuminated sites....
