Ethyl Group
The Ethyl Group (pronounced: /ˈɛθɪl/), is a functional group in organic chemistry, represented by the structural formula -C2H5 or -CH2CH3.
Etymology
The term "ethyl" was coined from the German "Aethyl", which was derived from the Greek "aither", meaning "upper air", and "hyle", meaning "matter".
Description
An ethyl group is an alkyl substituent derived from ethane (C2H6). It has the formula -C2H5 and is very often abbreviated Et. Ethyl is used in the IUPAC nomenclature of organic chemistry for a two-carbon moiety in a molecule, whilst the prefix "eth-" is used to denote the presence of two carbon atoms in the molecule.
