To determine whether the statement "Bromoethane reacts with silver nitrite to form ethyl nitrite" is true or false, we can analyze the reaction step by step. 1. Identify the Reactants : - The reactant is bromoethane (C2H5Br) and silver nitrite (AgNO2). 2. Understand the Reaction Mechanism : - Bromoethane is an alkyl halide, and silver nitrite ...
Nitroethane - Wikipedia
Alternatively, nitroethane can be produced by the Victor Meyer reaction of haloethanes such as chloroethane, bromoethane, or iodoethane with silver nitrite in diethyl ether or THF. The Kornblum modification of this reaction uses sodium nitrite in either a dimethyl sulfoxide or dimethylformamide solvent.

E. Substitution Reactions Involving Cyanide Ions
2023年1月23日 · The bromine (or other halogen) in the halogenoalkane is simply replaced by a -CN group - hence a substitution reaction. In this example, butanenitrile is formed. Here is the mechanism for the reaction involving bromoethane: This is an example ofnucleophilic substitution.
Bromoethane - Wikipedia
Bromoethane, also known as ethyl bromide, is a chemical compound of the haloalkanes group. It is abbreviated by chemists as EtBr (which is also used as an abbreviation for ethidium bromide). This volatile compound has an ether-like odor. The preparation of EtBr stands as a model for the synthesis of bromoalkanes in general.
