Ethyl halide shynthesis
WebChloroethane, 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. Ethyl chloride was first synthesised by Valentine by reacting ethanol and hydrochloric acid in 1440. ... WebThe acetyl group (highlighted in. Step 4: Determine the alkyl halide (s) needed for the reaction. In the acetoacetic acid synthesis, the enolate formed from ethyl acetoacetate will react with an alkyl halide in an SN2 reaction to form a carbon–carbon bond. In order to determine the alkyl halide (s) needed, first compare the starting material ...
