WebThis problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Question: 5) meta-Bromoaniline was treated with NaNO2 and HCl to yield a diazonium salt. Draw the product obtained when that diazonium salt is treated with each of the following reagents: H2O, HBF4, meta -Bromoaniline ... WebERROR: Reacting primary amines with nitrous acid yields diazonium salts which make for exceptional leaving groups (yields molecular nitrogen, N 2). The reaction is thus not useful for alkyl amines because a messy mixture of Sn1/E1 and other rearrangement products will result. ...

WebSubstitution reactions of diazonium ions. Diazonium ions are present in solutions such as benzenediazonium chloride solution. They contain an -N 2+ group. In the case of benzenediazonium chloride, this is attached to a benzene ring. In this set of reactions of the diazonium ion, the -N 2+ group is replaced by something else.
WebApr 8, 2024 · Diazonium Salts have the following properties: They have an ionic nature. They are soluble in water. Colorless crystalline solids, aryl diazonium salts are aryl diazonium salts. Water dissolves benzenediazonium chloride. However, it only reacts to it when it is warmed. Water does not dissolve benzenediazonium fluoroborate.
