what product is formed when the benzene is treated with hno3 and h2so4

by Braulio Ortiz Published 3 years ago Updated 3 years ago

Benzene reacts with concentrated nitric acid at 323-333k in the presence of concentrated sulphuric acid to form nitrobenzene. This reaction is known as nitration of benzene.

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 formed when benzene is treated with nitric and sulfuric acid?

The nironium ion is produced from sulphuric acid and the concentrated nitric acid: Nitronium ion is attacked by benzene to produce the product Nitrobenzene. Similarly, it is asked, is formed when benzene is treated with a mixture of nitric and sulfuric acid?

How is nitrobenzene formed from benzene?

Benzene is treated with a mixture of concentrated nitric acid and concentrated sulphuric acid at a temperature not exceeding 50°C. As temperature increases there is a greater chance of getting more than one nitro group, -NO2, substituted onto the ring. Nitrobenzene is formed.

How is benzene treated with acid?

Benzene is treated with a mixture of concentrated nitric acid and concentrated sulphuric acid at a temperature not exceeding 50°C. As temperature increases there is a greater chance of getting more than one nitro group, -NO2, substituted onto the ring.

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.

What happens when benzene is treated with conc H2SO4?

When Benzene reacts with H2SO4 the reaction is called sulphonation reaction (reaction with Conc. H2SO4 in the presence of SO3) it produce Benzenesulphonic acid(C6H5SO3H) and water.

What happens when HNO3 reacts with H2SO4?

There is no chemical reaction. H + NO3 and H2 + SO4 will give an equilibrium of the ions and the acid. Now, it is possible that if you add concentrated sulfuric acid to the nitric it can become hot enough to break the HNO3 into water and NO2 (gas). Has to do with heat, not a reaction between the two.

What is the product of reaction in which benzene is heated with concentrated sulphuric acid at 120 degree Celsius?

Benzene on heating with conc. H2SO4 gives benzene sulphonic acid which when heated with superheated steam under pressure gives benzene.

What happens when toluene is treated with conc HNO3 and H2SO4?

Conc. HNO3 and conc. H2SO4 is the reagent of nitration where nitronium ion acts as electrophile. Toluene undergoes nitration to give ortho and para nitrotoluene isomers, but if heated it can give dinitrotoluene and ultimately the explosive trinitrotoluene (TNT).

What is the reaction of benzene and conc.hno3?

Benzene react with conc hno3 in presence of conc.h2so4 to form C6H6NO2 . It is a electrophile substitution

What happens when phenol is reacted with H2SO4?

When phenol is reacted with conc. H2SO4 it will give ortho- & para- hydroxybenzenesulfonic acid.

What is the process of sulphohation of tolueneto?

A process for the sulphohation of tolueneto produce a product comprising chiefly p- toluene sulphonic acid which comprises refluxing a mixture of liquid toluene and concentrated sulphuric acid, the amount of toluene being in excess of that required to react with the acid, condensing the vapors evolved, separating water ...

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!

What is the source of nironium?

The nironium ion is produced from sulphuric acid and the concentrated nitric acid:

What can be used for nitration of C6H5BR?

However, in the nitration of C6H5Br we can use conc.HNO3 + conc.H2SO4 .

How to identify aromatic hydrocarbons?

In this case, most aromatic hydrocarbons can be identified by concentrated sulfuric acid. Concentrated sulfuric acid is added to the solution of the substance in alcohol or acetic acid anhydride. If there is an unsaturated group, a red, blue or purple color will occur.

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.

Why is 4-chlorobenzene sulfonic acid the major product?

But, 4-chlorobenzene sulfonic acid will be the major product due to symmetry and less steric hindrance .

What is the process of sulphohation of tolueneto?

A process for the sulphohation of tolueneto produce a product comprising chiefly p- toluene sulphonic acid which comprises refluxing a mixture of liquid toluene and concentrated sulphuric acid, the amount of toluene being in excess of that required to react with the acid, condensing the vapors evolved, separating water ...

Does ethylbenzene react faster than benzene?

That said, keep in mind that an ethyl group on a benzene rings activates it - that means, ethyl benzene will react faster than benzene itself. Moreover, it will activate the ring at 2 and 4 (ortho- and para-orientation).

How is nitrobenzene formed?

The formation of the electrophile. The electrophile is the "nitronium ion" or the "nitryl cation", NO2+. This is formed by reaction between the nitric acid and the sulphuric acid. The electrophilic substitution mechanism.

What is the reaction between nitric acid and benzene?

The electrophilic substitution reaction between benzene and nitric acid. The facts. Benzene is treated with a mixture of concentrated nitric acid and concentrated sulphuric acid at a temperature not exceeding 50°C. As temperature increases there is a greater chance of getting more than one nitro group, -NO2, substituted onto the ring.
