In organic chemistry, ozonolysis is an organic reaction where the unsaturated bonds are cleaved with ozone (O 3). Multiple carbon–carbon bond are replaced by carbonyl (C=O) groups, such as aldehydes, ketones, and carboxylic acids. The reaction is predominantly applied to alkenes, but alkynes and azo compounds are also susceptible to cleavage.
Methylpentene is an alkene with a molecular formula C 6 H 12.The prefix "methyl-" is derived from the fact that there is a methyl(CH 3) branch, the word root "-pent-" is derived from the fact that there are 5 carbon atoms in the parent chain, while the "-ene" suffix denotes that there is a double bond present, as per IUPAC nomenclature.

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 page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
2 Na + 2 C 5 H 6 → 2 NaC 5 H 5 + H 2. Aromatization can entail removal of hydride. Tropylium, C 7 H + 7 arises by the aromatization reaction of cycloheptatriene with hydride acceptors. C 7 H 8 + Br 2 → C 7 H + 7 + Br − + HBr Ciamician-Dennstedt rearrangement of a pyrrole to a pyridine. The first step involves dearomatization. The second ...
The Griesbaum coozonolysis is a name reaction in organic chemistry that allows for the preparation of tetrasubstituted ozonides (1,2,4-trioxolanes) by the reaction of O-methyl oximes with a carbonyl compound in the presence of ozone.
Tetramethylammonium ozonide, which can be made by a metathesis reaction with caesium ozonide in liquid ammonia, is stable up to 348 K (75 °C): [4] CsO 3 + [(CH 3) 4 N][O 2] → CsO 2 + [(CH 3) 4 N][O 3] Alkaline earth metal ozonide compounds have also become known. For instance, magnesium ozonide complexes have been isolated in a low ...
As determined by the enthalpies below the corresponding molecules, the enthalpy of reaction for 2-methyl-1-butene going to 2-methyl-butane is −29.07 kcal/mol, which is in great agreement with the value calculated from NIST, [15] −28.31 kcal/mol. For 2-butanone going to 2-butanol, enthalpy of reaction is −13.75 kcal/mol, which again is in ...
