Benzaldehyde Preparation Toluene: Benzaldehyde is obtained from oxidation of toluene by chromyl chloride CrO2Cl2. This reaction is called Etard’s Reaction.C6H5CH3 + 2CrO2Cl2 → C6H5CH(OCrOHCl2)2 → C6H5CHOBenzaldehyde is also obtained by oxidation…
Phenol is also called carbolic acid. The compounds in which the -OH group is directly attached to the benzene ring are called phenols or phenolic compounds and under these conditions…
Benzenesulfonic acid Preparation Benzenesulfonic acid is obtained from sulphonation of benzene. For this, benzene is heated with concentrated Sulfuric acid.C6H6 + H2SO4(concentrated) → C6H5SO3H + H2O Laboratory Method To make…
Aniline Preparation Laboratory method: from tin and HCl reduction of nitrobenzene: in the laboratory, aniline is made by the reduction of nitrobenzene by tin and HCl. Sn + 4HCl → SnCl4 +…
Nitrobenzene Preparation Nitrobenzene is obtained from the nitration of benzene. For this, benzene is heated to about 60°C with a mixture of concentrated HNO3 and concentrated H2SO4. A hydrogen atom…
Preparation Laboratory Method Aniline: Benzenediazonium chloride is obtained by replicating aniline with a mixture of NaNO2 and HCl at 0-5°C. Chlorobenzene is obtained by heating benzenediazonium chloride in the presence…
