What is the purpose of using sulfuric acid in the nitration of benzene quizlet?

What is the purpose of using sulfuric acid in the nitration of benzene quizlet?

The sulfuric acid serves as a catalyst and promotes the loss of water from nitric acid to give the nitronium ion (NO2+). The nitronium ion then goes on to act as the electrophile species that adds to the pie system of the aromatic ring.

Is sulfuric acid a catalyst in nitration of benzene?

The concentrated sulphuric acid is acting as a catalyst. The electrophile is the “nitronium ion” or the “nitryl cation”, NO2+.

What is the action of concentrated sulphuric acid on benzene?

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.

Which of these compounds would react faster in a nitration reaction quizlet?

Methylbenzene would react faster in nitration than nitrobenzene would.

What organic product is formed when benzene reacts with nitric acid in the presence of concentrated sulfuric acid quizlet?

Benzene will react with hot concentrated nitric acid to produce nitrobenzene.

What is role of Sulphuric acid in nitration?

Sulfuric acid is needed in order for a good electrophile to form. 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.

What is the use of sulphuric acid in nitration process?

Sulfuric acid is needed in order for a good electrophile to form. 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.

When benzene reacts with fuming sulfuric acid which species is most likely to be the electrophile?

sulphur trioxide
The electrophile is actually sulphur trioxide, SO3, and you may find the equation for the sulphonation reaction written: Note: Which version of this equation you use will depend on what question you are being asked. If the question refers to the reaction with sulphuric acid, then you must use that one.

What is the role of sulphuric acid in nitration?

Sulphuric acid is necessary as it helps in the generation of nitronium ion from nitric acid which is the actual nitrating agent. Nitronium ion is not easily generated when we use only nitric acid. What is the role of sulphuric acid in nitration of benzene?

Why does benzene react with nitric acid to produce nitrobenzene?

Because the nitronium ion is a good electrophile, it is attacked by benzene to produce Nitrobenzene. Nitric acid reacts with the sulphuric acid which leads to producing the strong nitronium ion. The double bond in the benzene attacks the nitronium ion at the + charge to form a new covalent bond to the nitrogen atom.

What is the source of nitronium ion in benzene?

The source of the nitronium ion is through the protonation of nitric acid by sulfuric acid, which causes the loss of a water molecule and formation of a nitronium ion. The first step in the nitration of benzene is to activate HNO3 with sulfuric acid to produce a stronger electrophile, the nitronium ion.

Why is H2SO4 used in nitration?

Why H2SO4 is used in Nitration In the protonation of nitric acid by sulfuric acid, the source of the nitronium ion induces the removal of a water molecule and the creation of a nitronium ion. The first step in benzene nitration is to activate HNO 3 with sulfuric acid to create a nitronium ion, a stronger electrophile.
