Diethyl ether, or simply ether, is an organic compound with the chemical formula (CH 3 CH 2) 2 O, sometimes abbreviated as Et 2 O. [ a ] It is a colourless, highly volatile , sweet-smelling ("ethereal odour"), extremely flammable liquid .
Diethyl ether is simply called ether, but was once called sweet oil of vitriol. Methyl phenyl ether is anisole, because it was originally found in aniseed. The aromatic ethers include furans. Acetals (α-alkoxy ethers R–CH(–OR)–O–R) are another class of ethers with characteristic properties.

Alchemist Ramon Llull has been credited with discovering diethyl ether in 1275. [citation needed] [74] Aureolus Theophrastus Bombastus von Hohenheim (1493–1541), better known as Paracelsus, discovered the analgesic properties of diethyl ether around 1525. [75] It was first synthesized in 1540 by Valerius Cordus, who noted some of its ...
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).
