Sulfuric acid is used in aromatic nitration because it acts as a catalyst, helping to facilitate the reaction between the aromatic compound and nitric acid. This reaction is important for introducing nitro groups into the aromatic compound, which can lead to the formation of various nitroaromatic compounds with important industrial applications.

Why is sulfuric acid used in aromatic nitration?
Sulfuric acid is used in aromatic nitration as a catalyst and as a source of protons to initiate the nitration reaction. It helps to activate the nitric acid by protonating it, making it a better electrophile. Additionally, sulfuric acid helps to absorb the water produced during the nitration process, which can improve the yield of the desired nitro compound.
What is nitration process?
Nitration is a chemical reaction where a nitro group (NO₂) is added to a molecule. It is often used to introduce this functional group into organic compounds to produce substances like nitrobenzene or TNT. The reaction is typically carried out using a mixture of nitric acid and sulfuric acid as the nitrating agent.
What is nitric and sulfuric acid also known as?
Nitric acid = Aqua Fortis, Spirit of Nitre Sulfuric acid = Oil of Vitriol, or simply Vitriol
What is the role of sulfuric acid in this synthesis( why will nitration be less effective if only nitric acid alone is used?
Sulfuric acid serves as a catalyst in the nitration reaction, facilitating the generation of the nitronium ion (NO2+). Without the sulfuric acid, the nitric acid alone would not be able to efficiently produce the nitronium ion, leading to a less effective nitration reaction. Additionally, sulfuric acid helps to protonate the substrate, making it more reactive towards electrophilic substitution by the nitronium ion.
What is nitration mixture?
A nitration mixture is a combination of nitric acid and sulfuric acid used in chemical reactions to introduce a nitro group (NO2) onto an organic molecule. The sulfuric acid serves as a catalyst and dehydrating agent, while the nitric acid supplies the nitro group for the reaction. It is commonly used in the synthesis of nitroaromatic compounds.

What are the results when vasopressin is tested with xanthoproteic?
xanthoproteic test is used to detect the presence of aromatic amino acid in this nitration of an benzee ring with nitric acid takes place.
Why will nitration be less effective if only nitric (IV) acid alone is used?
Nitration will be less effective with only nitric (IV) acid (HNO₂) because it is a weaker nitrating agent compared to a mixture of nitric (V) acid (HNO₃) and sulfuric acid (H₂SO₄). The stronger oxidizing properties of nitric (V) acid facilitate the generation of the nitronium ion (NO₂⁺), which is the active electrophile in nitration reactions. Without sulfuric acid to protonate nitric acid and enhance the production of the nitronium ion, the reaction rate will be significantly reduced. Thus, the presence of both acids is essential for efficient nitration.
Why direct nitration is used in picric acid?
in picric acid we cannot used direct nitration because of the phenol is very sensitive in oxidation of nitrate, to overcome this problem, we used a sulfuric acid added to phenol before the nitric acid. the reaction between NO2 and SO2 are reversible so the sulphate exchange with nitrate becoming tri nitrophenol
Reactant used to synthesize nitrobenzene?
Nitrobenzene is typically synthesized by nitration of benzene using a mixture of concentrated nitric acid and sulfuric acid as the nitrating agents. The reaction involves the substitution of a hydrogen atom on the benzene ring with a nitro group, resulting in the formation of nitrobenzene.
What is the procedure for synthesis of 3-nitrobenzaldehyde?
Check the book Macroscale and Microscale by Williamson and Masters. Go to the chapter entitled Nitration of Methyl Benzoate. The synthesis of 3-nitrobenzaldehyde/3-nitrobenzoic acid has the same procedure.
What is the reaction of benzene with HCl?
Nitration: H2SO4 C6H6 + HONO2 ---------> C6H5NO2 + H2O Nitric Acid Nitrobenzene Nitration: H2SO4 C6H6 + HONO2 ---------> C6H5NO2 + H2O Nitric Acid Nitrobenzene Nitration: .................H2SO4 C6H6 + HONO2 ---------> C6H5NO2 + H2O .....Nitric Acid ......Nitrobenzene
Is h2so4 a acid or base?
H2SO4 is a strong acid known as sulfuric acid
