Ethylene is widely used in the chemical industry, and its worldwide production (over 150 million tonnes in 2016 [8]) exceeds that of any other organic compound. [ 9 ] [ 10 ] Much of this production goes toward creating polythene , which is a widely used plastic containing polymer chains of ethylene units in various chain lengths.

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. It is unstable in its pure form and thus is usually handled as a solution. [9]

In condensed structural formulas, many or even all of the covalent bonds may be left out, with subscripts indicating the number of identical groups attached to a particular atom. Another shorthand structural diagram is the skeletal formula (also known as a bond-line formula or carbon
Ethylene oxide is an organic compound with the formula C 2 H 4 O. It is a cyclic ether and the simplest epoxide : a three-membered ring consisting of one oxygen atom and two carbon atoms. Ethylene oxide is a colorless and flammable gas with a faintly sweet odor.
A chemical formula specifies the number of atoms of each element in a compound molecule, using the standard chemical symbols with numerical subscripts. Many chemical compounds have a unique CAS number identifier assigned by the Chemical Abstracts Service. Globally, more than 350,000 chemical compounds (including mixtures of chemicals) have been ...
