Ethyl group
<templatestyles src="Module:Hatnote/styles.css"></templatestyles>
In chemistry, an ethyl group is an alkyl substituent derived from ethane (C2H6). It has the formula –CH2CH3 and is very often abbreviated Et. Ethyl is used in the IUPAC nomenclature of organic chemistry for a saturated two-carbon moiety in a molecule, whilst the prefix "eth-" is used to indicate the presence of two carbon atoms in the molecule.

Ethylation
Ethylation is the formation of a compound by introduction of the ethyl group. The most widely practiced example of this reaction is the ethylation of benzene. The ethylating agent is ethylene.
Approximately 24.7 million tons were produced in 1999.[1] Ethylbenzene is the precursor to styrene, the precursor to polystyrene.
Etymology
The name of the group is derived from the Aether, the first-born Greek elemental god of air, and "hyle", referring to "stuff".
