For example, ethyl methyl ether (CH 3 OC 2 H 5), diphenylether (C 6 H 5 OC 6 H 5). As for other organic compounds, very common ethers acquired names before rules for nomenclature were formalized. 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 ...
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 .
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). Ethyl is used in the International Union of Pure and Applied Chemistry 's nomenclature of organic chemistry for a saturated two-carbon moiety in a molecule, while the prefix " eth- " is used to indicate the ...
Chemical structure of the vinyl functional group. 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.
