Question

Short note on nitration reaction.

Answer 1

Answer :

Nitration -

The process of substituting nitro group over benzene ring by treatment of Benzene with concentrate $HNO_3$ in presence of concentrate $H_2SO_4$ are known as nitration reaction.

Benzene + Nitric Acid $\longrightarrow$ Nitro Benzene + Water

Mechanism -

Mechanism of above reaction takes place in following three steps :

1. In this step the generation of electrophile takes place.

2. In second step, electrophile attacks over benzene ring to give a resonance stabilized carbocation.

3. In this step, resonance stabilized carbocation looses proton to give final product.

Answer 2

HEYA!
ANSWER - :
Nitration is the process of adding a nitro group to an organic substrate. The most common form of nitration is adding the nitro group to an aromatic ring system. The nitration reaction mechanism involves: Formation of the nitronium ion by the action of nitric and sulfuric acids.
