What is the reaction of benzene with a mixture of HNO3 and H2SO4?
Originally Answered: What is the reaction of benzene with a mixture of concentrated HNO3 and concentrated H2SO4? This mixture produces the strong electrophile “the nitronium ion”. The nironium ion is produced from sulphuric acid and the concentrated nitric acid:
What is the product formed when benzene reacts with sulphuric acid?
This mixture produces the strong electrophile “the nitronium ion”. The nironium ion is produced from sulphuric acid and the concentrated nitric acid: Nitronium ion is attacked by benzene to produce the product Nitrobenzene.

What happens when benzene is heated with conc HNO3 and conc H2SO4?
HNO3+ Conc. H2SO4 (nitrating mixture) reacts with benzene to give nitrobenzene at 323K and m-dinitrobenzene at 373K.
What happens when benzene is treated with mixture of conc sulphuric acid and conc nitric acid at 330 K?
Explanation: Benzene when treated with concentrated nitric acid and sulfuric acid at 330K temperature it forms nitrobenzene that is nitration occurs. The reaction is highly explosive and risky as a lot of heat is evolved during the reaction.
Is formed when benzene is treated with a mixture of nitric and sulfuric acid?
nitrobenzeneThe nitration of benzene Benzene is treated with a mixture of concentrated nitric acid and concentrated sulfuric acid at a temperature not exceeding 50°C. The mixture is held at this temperature for about half an hour. Yellow oily nitrobenzene is formed.
What does HNO3 and H2SO4 do?
Sulfuric Acid Activation of Nitric Acid The first step in the nitration of benzene is to activate HNO3with sulfuric acid to produce a stronger electrophile, the nitronium ion. Because the nitronium ion is a good electrophile, it is attacked by benzene to produce Nitrobenzene.
What happens when benzene is treated with conc H2SO4?
C6H6+H2SO4→C6H5SO3H+H2O.
What happens when benzene reacts with H2SO4?
C6H6+H2SO4→C6H5SO3H+H2O.
Which of the following is the product of benzene with HNO3 using H2SO4 as a catalyst?
H2SO4 + HNO3 + C6H6 | Nitration of Benzene. When benzene is heated with concentrated sulfuric acid ( H2SO4) and concentrated nitric (HNO3) acid, nitrobenzene is given as the product.
How no2+ is formed?
The concentrated sulphuric acid is acting as a catalyst. The electrophile is the "nitronium ion" or the "nitryl cation", NO2+. This is formed by reaction between the nitric acid and the sulphuric acid.
How is nitrobenzene formed?
Nitrobenzene is prepared by nitration of benzene with a mixture of concentrated sulfuric acid, water, and nitric acid.
What is halogenation of benzene?
The halogenation of benzene Benzene reacts with chlorine or bromine in the presence of a catalyst, replacing one of the hydrogen atoms on the ring by a chlorine or bromine atom. The reactions happen at room temperature.
What is the nironium ion produced from?
The nironium ion is produced from sulphuric acid and the concentrated nitric acid: Nitronium ion is attacked by benzene to produce the product Nitrobenzene. Diagrams were taken from the article cited below; which is an excellent read! Nitration and Sulfonation of Benzene. Here is something for you to look up!
Does sulfuric acid react with benzene?
Yes, the reaction of benzene and fuming sulfuric acid (a mixture of SO3 and concentrated sulfuric acid) results in sulfonation. The reaction is shown below. Because the reaction mechanism involves electrophilic aromatic substitution (EAS) and that the -SO3H group deactivates the ring to EAS, only one -SO3H group is typically added.
What is the mixture of HNO3 and H2SO4?
Mixture of conc. HNO3 + conc. H2SO4 is called nitrating mixture. When chlorobenzene is treated with nitrating mixture, nitration will occur. Halogens are ortho and para directing so we will get a mixture of.
What is the nironium ion?
This mixture produces the strong electrophile “the nitronium ion”. The nironium ion is produced from sulphuric acid and the concentrated nitric acid: Nitronium ion is attacked by benzene to produce the product Nitrobenzene.
