What happens when chlorobenzene is treated with conc H2SO4?

When benzene is heated with fuming sulphuric acid or concentrated sulphuric acid, it yields benzene sulphonic acid. Complete step by step answer: In this reaction, chlorobenzene reacts with sulfuric acid and gives o and p chlorobenzenesulfonic acid. Further, the sulphonation of benzene is a reversible reaction.

What happens when benzene reacts with concentrated HNO3 and concentrated H2SO4?

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 happens when HNO3 reacts with H2SO4?

Sulfuric acid protonates nitric acid to form the nitronium ion (water molecule is lost). The nitronium ion is a very good electrophile and is open to attack by benzene. Without sulfuric acid the reaction would not occur. 4.

What happens when benzene is treated with mixture of conc H2SO4 and conc HNO3 at 330K?

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 is the action of 1 conc hno3 on chlorobenzene?

When chlorobenzene reacts with concentrated nitric acid, the process of nitration takes place.

What happens when benzene reacts with conc hno3 in the presence of conc h2so4 at 600?

When benzene is heated with concentrated sulfuric acid ( H2SO4) and concentrated nitric (HNO3) acid, nitrobenzene is given as the product. A hydrogen atom of benzene is replaced by a nitro group (-NO2) in this reaction.

What happens when benzene is heated with conc h2so4?

Heating benzene with conc. sulphuric acid for a few hours results in the formation of benzenesulphonic acid. This reaction is an electrophilic substitution reaction.

What happens when benzoic acid reacts with conc HNO3 and H2SO4?

When benzoic acid reacts with concentrated nitric and sulphuric acid, it forms m-nitrobenzoic acid. Benzoic acid is an aromatic compound containing carboxylic acid as a functional group.

What happens when benzene is treated with conc HNO3?

On reaction with concentrated Nitric Acid, Benzene gets converted into nitrobenzene. This phenomena is usually known as nitration of benzene.

What happens when benzene is treated with nitrating mixture?

Benzene is treated with a mixture of concentrated nitric acid and concentrated sulphuric 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. Some of the nitrobenzene formed reacts with the nitrating mixture of concentrated acids.

What happens when benzene is heated with H2SO4 and HNO3?

When benzene is heated with concentrated sulfuric acid ( H 2 SO 4) and concentrated nitric (HNO 3) acid, nitrobenzene is given as the product. A hydrogen atom of benzene is replaced by a nitro group (-NO 2) in this reaction. In this tutorial, we will learn followings.

What happens when chlorobenzene is treated with sulphuric acid?

When Chlorobenzene is treated with sulphuric acid o-Chlorobenzene sulfonic acid and p- Chlorobenzene sulphonic acid will form . But, 4-chlorobenzene sulfonic acid will be the major product due to symmetry and less steric hindrance .

What is the electrophile that reacts with chlorobenzene?

The nitronium ion, N O+ 2, is the electrophile that reacts with chlorobenzene (to give nitrochlorobenzene and sulfuric acid); the bisulfate ion is the base that removes H + from the nitrated ring.

What happens when protonated nitric acid reacts with benzene?

The protonated nitric acid LOSES water to form the LINEAR nitronium ion, A POTENT ELECTROPHILE…that is capable of reaction with the nucleophilic benzene ring… Is H2SO4 more acidic than HNO3?
