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 is the role of sulphuric acid in the synthesis of Nitro benzene?
Sulfuric acid acts as a catalyst in the synthesis of nitrobenzene by nitrating benzene. It facilitates the nitration reaction by protonating the nitric acid, making it a better electrophile for attacking the benzene ring. Sulfuric acid also helps in generating the nitronium ion, which is the active species involved in the nitration process.
How much quantity nitric acid and sulfuric acid in nitration mixture?
The typical nitration mixture consists of concentrated sulfuric acid and nitric acid in a specific ratio, such as a 3:1 mixture of sulfuric acid to nitric acid to allow for nitration reactions to occur effectively. The exact quantities may vary depending on the specific reaction being carried out and the desired outcome. It is important to consult a protocol or experienced chemist for the precise amounts needed for a particular nitration reaction.
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.

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.

What is the function of sulphuric acid in the nitration of benzene?
Sulfuric acid acts as a catalyst in the nitration of benzene by protonating the nitric acid, which generates a more reactive electrophile (NO2+). This electrophile then attacks the benzene ring to introduce the nitro group during the nitration process.

Why add nitric acid and sulphuric acid to acetanilide?
Nitric acid and sulfuric acid are added to acetanilide to facilitate the nitration reaction. Nitric acid provides the nitronium ion needed for nitration, while sulfuric acid acts as a catalyst and helps in protonating the acetanilide molecule. This process allows for the substitution of a nitro group onto the acetanilide molecule.
Why is sulfuric acid used in aromatic nitration?
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.
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.
