WitrynaThe aromatic compound A is benzoic acid C 6H 5COOH. On treatment with aqueous ammonia and heating forms compound B, which is benzamide C 6H 5CONH 2. Benzamide on heating with bromine and KOH forms a compound C of molecular formula C 6H 7N, which is aniline C 6H 5NH 2. The reaction is called Hoffmann bromamide … Witryna23 sty 2024 · The halogenoalkane is heated under reflux with a solution of sodium or potassium hydroxide. Heating under reflux means heating with a condenser placed vertically in the flask to prevent loss of volatile substances from the mixture. The solvent is usually a 50/50 mixture of ethanol and water, because everything will dissolve in that.
