In the mid-19th century, the suffix -ene (an Ancient Greek root added to the end of female names meaning "daughter of") was widely used to refer to a molecule or part thereof that contained one fewer hydrogen atoms than the molecule being modified. Thus, ethylene (C 2 H 4) was the "daughter of ethyl" (C 2 H 5). The name ethylene was used in ...
In chemistry, vinylene (also ethenylene or 1,2-ethenediyl) [1] is a divalent functional group (a part of a molecule) [2] with formula −CH=CH−; [3] namely, two carbons, each connected to the other by a double bond, to an hydrogen atom by a single bond, and to the rest of the molecule by another single bond.
In organic chemistry, a vinyl group (abbr. Vi; [1] IUPAC name: ethenyl group [2]) is a functional group with the formula −CH=CH 2. It is the ethylene (IUPAC name: ethene) molecule (H 2 C=CH 2) with one fewer hydrogen atom. The name is also used for any compound containing that group, namely R−CH=CH 2 where R is any other group of atoms.

RCH=CH 2 + RCO 3 H → RCHOCH 2 + RCO 2 H. For ethylene, the epoxidation is conducted on a very large scale industrially using oxygen in the presence of silver-based catalysts: C 2 H 4 + 1/ 2 O 2 → C 2 H 4 O. Alkenes react with ozone, leading to the scission of the double bond. The process is called ozonolysis.
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 ...
2 C 2 H 6 + 7 O 2 → 4 CO 2 + 6 H 2 O + 3120 kJ. Combustion may also occur without an excess of oxygen, yielding carbon monoxide, acetaldehyde, methane, methanol, and ethanol. At higher temperatures, especially in the range 600–900 °C (1,112–1,652 °F), ethylene is a significant product: 2 C 2 H 6 + O 2 → 2 C 2 H 4 + 2 H 2 O
In Zeise's salt K[PtCl 3 (C 2 H 4)]. H 2 O the C−C bond length has increased to 134 picometres from 133 pm for ethylene. In the nickel compound Ni(C 2 H 4)(PPh 3) 2 the value is 143 pm. The interaction also causes carbon atoms to "rehybridise" from sp 2 towards sp 3, which is indicated by the bending of the hydrogen atoms on the ethylene back ...
