2-Methyl-2-butene (CAS 513-35-9) Index of chemical compounds with the same molecular formula This set index page lists chemical structure articles associated with the same molecular formula .
For example, the relative rates of epoxidation increase upon methyl substitution of the alkene (the methyl groups increase the electron density of the double bond by hyperconjugation): ethylene (1, no methyl groups), propene (24, one methyl group), cis-2-butene (500, two methyl groups), 2-methyl-2-butene (6500, three methyl groups), 2,3 ...
Acetylene (systematic name: ethyne) is the chemical compound with the formula C 2 H 2 and structure H−C≡C−H.It is a hydrocarbon and the simplest alkyne. [8] This colorless gas is widely used as a fuel and a chemical building block.
As of 2010s, the only commercial manufacturer of 1-pentene was Sasol Ltd., where it is separated from crude by the Fischer-Tropsch process. [2] 2-Pentene has two geometric isomers: cis-2-pentene and trans-2-pentene. Cis-2-Pentene is used in olefin metathesis.
This mechanism is today considered the actual mechanism taking place in olefin metathesis. Chauvin's experimental evidence was based on the reaction of cyclopentene and 2-pentene with the homogeneous catalyst tungsten(VI) oxytetrachloride and tetrabutyltin: The three principal products C9, C10 and C11 are found in a 1:2:1 regardless of conversion.

1,2-Dichloroethylene or 1,2-DCE is the name for a pair of organochlorine compounds with the molecular formula C 2 H 2 Cl 2. The two compounds are isomers, each being colorless liquids with a sweet odor. It can exist as either of two geometric isomers, cis-1,2-dichloroethene or trans-1,2-dichloroethene, but is often used as a mixture of the two ...
Type I dyotropic rearrangements also occur around carbon-oxygen bonds, such as the thermal equilibration of (R 3 Si 1)R 2 C-O-Si 2 R 3 to (R 3 Si 2)R 2 C-O-Si 1 R 3. [6]: 36 The 1,2-Wittig rearrangement can also be considered an example of this reaction type. More dyotropic reactions are found involving N-O bonds and N-N bonds.
