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 ).
Ethane (US: / ˈ ɛ θ eɪ n / ETH-ayn, UK: / ˈ iː θ eɪ n / EE-thayn) is a naturally occurring organic chemical compound with chemical formula C 2 H 6. At standard temperature and pressure, ethane is a colorless, odorless gas. Like many hydrocarbons, ethane is isolated on an industrial scale from natural gas and as a petrochemical by ...
The equation of bromination of ethylene to form ethane is: H 2 C=CH 2 + Br 2 →H 2 CBr−CH 2 Br. Unlike hydrogenation, these halogenation reactions do not require catalysts. The reaction occurs in two steps, with a halonium ion as an intermediate. Structure of a bromonium ion. Bromine test is used to test the saturation of hydrocarbons. [17]
Aromatic compounds, almost uniquely for hydrocarbons, undergo substitution reactions. The chemical process practiced on the largest scale is the reaction of benzene and ethene to give ethylbenzene: C 6 H 6 + C 2 H 4 → C 6 H 5 CH 2 CH 3
Ethylene oxide is an organic compound with the formula C 2 H ... Reaction of ethylene oxide with sulfur dioxide in the presence of ... reaction of diiodo ethane with ...
1,2-Diiodoethane can be prepared by the reaction of ethylene with iodine (I 2): [2] C 2 H 4 + I 2 ⇌ C 2 H 4 I 2. 1,2-Diiodoethane is most commonly used in organic synthesis in the preparation of samarium(II) iodide or ytterbium(II) iodide in an inert solvent such as THF. [3] Sm + ICH 2 CH 2 I → SmI 2 + H 2 C=CH 2
Ethyl group (highlighted blue) as part of a molecule, as the ethyl radical, and in the compounds ethanol, bromoethane, ethyl acetate, and ethyl methyl ether.. In organic chemistry, an ethyl group (abbr. Et) is an alkyl substituent with the formula −CH 2 CH 3, derived from ethane (C 2 H 6).
Chloroethane is produced by hydrochlorination of ethylene: [11]. C 2 H 4 + HCl → C 2 H 5 Cl. At various times in the past, chloroethane has also been produced from ethanol and hydrochloric acid, from ethane and chlorine, or from ethanol and phosphorus trichloride, but these routes are no longer economical.
