Aniline is a primary amine (contains -NH2 group). When it is treated with chloroform under alkaline conditions, it results in the formation of a bad smelling compound, known by the name isonitrile or carbylamine. This reaction is known as carbylamine reaction.
When phenol is treated with D2SO4 /D2O, some of the hydrogens get exchanged.The final product in this exchange reaction is
