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).
The "eth-" prefix and the qualifier "ethyl" in "ethyl alcohol" originally came from the name "ethyl" assigned in 1834 to the group C 2 H 5 − by Justus Liebig. He coined the word from the German name Aether of the compound C 2 H 5 −O− C 2 H 5 (commonly called "ether" in English, more specifically called "diethyl ether"). [21]

A cycloalkyl group is derived from a cycloalkane by removal of a hydrogen atom from a ring and has the general formula −C n H 2n−1. [2] Typically an alkyl is a part of a larger molecule. In structural formulae, the symbol R is used to designate a generic (unspecified) alkyl group. The smallest alkyl group is methyl, with the formula −CH 3 ...
For example, the isopropyl group (IUPAC: prop-2-yl) −CH(CH 3) 2 corresponds to the isopropylidene group =C(CH 3) 2 (IUPAC: prop-2-ylidene). The group is not typically used in common names of branched alkenes - e.g. 3-methylenepentane, the simplest compound that systematically includes an alkylidene group, [Note 1] is commonly known as 2-ethyl ...
An ester of carboxylic acid.R stands for any group (organic or inorganic) and R′ stands for organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (−R).
Ethylmercury (sometimes ethyl mercury) is a cation composed of an organic CH 3 CH 2 — species (an ethyl group) bound to a mercury(II) centre, making it a type of organometallic cation, and giving it a chemical formula C 2 H 5 Hg +. The main source of ethylmercury is thimerosal. [1]
N-Ethylhexedrone is a derivative of hexedrone, in which the methyl group attached to the nitrogen atom is substituted by an ethyl group.It is structurally similar to pentedrone, and also α-pyrrolidinohexiophenone (), from which it differs by the substitution of a pyrrolidine group with an N-ethyl group.
