Ethylene (IUPAC name: ethene) is a hydrocarbon which has the formula C 2 H 4 or H 2 C=CH 2.It is a colourless, flammable gas with a faint "sweet and musky" odour when pure. [7] It is the simplest alkene (a hydrocarbon with carbon–carbon double bonds).

The reaction occurs easier with the last two acids: (CH 2 CH 2)O + HCl → HO–CH 2 CH 2 –Cl. The reaction with these acids competes with the acid-catalyzed hydration of ethylene oxide; therefore, there is always a by-product of ethylene glycol with an admixture of diethylene glycol. For a cleaner product, the reaction is conducted in the ...
Global ethane emission rates declined from 1984 to 2010, [27] though increased shale gas production at the Bakken Formation in the U.S. has arrested the decline by half. [ 28 ] [ 29 ] Although ethane is a greenhouse gas , it is much less abundant than methane, has a lifetime of only a few months compared to over a decade, [ 30 ] and is also ...
The reaction equation for hydration of ethylene is: H 2 C=CH 2 + H 2 O→ H 3 C-CH 2 OH Example of hydrohalogenation: addition of HBr to an alkene. Hydrohalogenation involves addition of H−X to unsaturated hydrocarbons. This reaction results in new C−H and C−X σ bonds. The formation of the intermediate carbocation is selective and ...
The cycle is concerned with the formation of an ionic compound from the reaction of a metal (often a Group I or Group II element) with a halogen or other non-metallic element such as oxygen. Born–Haber cycles are used primarily as a means of calculating lattice energy (or more precisely enthalpy [note 1]), which cannot otherwise be measured ...
Structure of (acac)Rh(C 2 H 4)(C 2 F 4), distances (red) in picometers. [3]The bonding between alkenes and transition metals is described by the Dewar–Chatt–Duncanson model, which involves donation of electrons in the pi-orbital on the alkene to empty orbitals on the metal.
Ethylbenzene is an organic compound with the formula C 6 H 5 CH 2 CH 3.It is a highly flammable, colorless liquid with an odor similar to that of gasoline.This monocyclic aromatic hydrocarbon is important in the petrochemical industry as a reaction intermediate in the production of styrene, the precursor to polystyrene, a common plastic material.
