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 and sulfuric acid together are commonly known as nitration mixture. This mixture is highly corrosive and used in various organic synthesis reactions involving nitration.
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.
Why direct nitration is used in picric acid?
Direct nitration is used in picric acid synthesis to introduce nitro groups onto the benzene ring. This method involves the direct reaction of benzene with a nitrating agent, usually a nitric acid/sulfuric acid mixture, leading to the controlled introduction of nitro groups at specific positions on the benzene ring to form picric acid.

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.

This method involves the direct reaction of benzene with a nitrating agent, usually a nitric acid/sulfuric acid mixture, leading to the controlled introduction of nitro groups at specific positions on the benzene ring to form picric acid.
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?
3-nitrobenzaldehyde can be synthesized by nitration of benzaldehyde with nitric acid in the presence of a catalyst such as sulfuric acid. The reaction is typically carried out under controlled conditions to avoid excessive nitration. After the reaction, purification techniques such as recrystallization can be used to isolate the final product.
What is the reaction of benzene with HCl?
Benzene does not undergo a direct reaction with hydrochloric acid (HCl) under normal conditions because benzene is a stable aromatic compound. However, benzene can be chlorinated in the presence of a catalyst such as aluminum chloride to form chlorobenzene, which can then react with HCl to form phenol under certain conditions.
Is h2so4 a acid or base?
H2SO4 is an acid. It is known as sulfuric acid, which is a strong mineral acid commonly used in various industries.
What is the most used acid in the world?
