Chloroethane, commonly known as ethyl chloride, is a chemical compound with chemical formula CH 3 CH 2 Cl, once widely used in producing tetraethyllead, a gasoline additive. It is a colorless, flammable gas or refrigerated liquid with a faintly sweet odor.
Simple molecules have simple spectra. The spectrum of ethyl chloride consists of a triplet at 1.5 ppm and a quartet at 3.5 ppm in a 3:2 ratio. The spectrum of benzene consists of a single peak at 7.2 ppm due to the diamagnetic ring current. Together with carbon-13 NMR, proton NMR is a powerful tool for molecular structure characterization.

Tetraethylammonium chloride (TEAC) is a quaternary ammonium compound with the chemical formula [N(CH 2 CH 3) 4] + Cl −, sometimes written as [NEt 4]Cl. In appearance, it is a hygroscopic, colorless, crystalline solid.
Also compounds, such as high temperature silicone "stopcock" grease, which have polysiloxanes (often called silicones) in them will commonly show peaks from their methyl groups (attached to the silicon atoms) having NMR chemical shifts close to the tetramethylsilane standard peak, such as at 0.07 ppm in CDCl 3.
Methyl, ethyl, and other alkyl or aralkyl halides that are not dehydrohalogenated readily can react with aluminium in an exothermic process to form organoaluminium sesquihalides in high yields. An important example is the reaction of ethyl chloride with aluminium to form ethylaluminium sesquichloride. 3 C 2 H 5 Cl + 2 Al → (C 2 H 5) 3 Al 2 Cl 3
In the laboratory it is occasionally used as a source of chlorine, with elimination of ethene and chloride. Via several steps, 1,2-dichloroethane is a precursor to 1,1,1-trichloroethane . Historically, before leaded petrol was phased out, chloroethanes were used as an additive in petrol to prevent lead buildup in engines.
Ethyl chloroformate is an organic compound with the chemical formula ClCO 2 CH 2 CH 3. It is the ethyl ester of chloroformic acid. It is a colorless, corrosive and highly toxic liquid. It is a reagent used in organic synthesis for the introduction of the ethyl carbamate protecting group [3] and for the formation of carboxylic anhydrides.
