What is the reaction between aniline and chlorine?
Aniline reacts with liquid chlorine to give 2-4-6-trichloroaniline. This reaction is used to prepare phenol or benzene diazonium chloride. Sodium nitrite and dilute hydrochloric acid ( NaNO 2 and HCl ) are mixed to prepare nitrous acid (HNO 2 ). According to the temperature, phenol or benzene diazonium chloride is given.
What happens when sulfuric acid reacts with aniline?
In the presence of sulfuric acid (pKa = -5.5) aniline will be protonated (anilinium ion pKa = 4.63). That changes the electron-donating amino group to an electron-withdrawing ammonium ion. The reaction will require higher temperature as well.
What happens when Aniline reacts with chloroform under alkaline conditions?
The reaction of aniline with chloroform under alkaline conditions leads to the formation of Aniline is a primary amine (contains -NH 2 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.
