The process is one example of electrophilic aromatic substitution, which involves the attack by the electron-rich benzene ring: Alternative mechanisms have also been proposed, including one involving single electron transfer (SET). Nitration of Benzene. The overall reaction for the nitration of methyl benzoate. Common benzene reactions are Nitration of Benzene.

Reaction type: Electrophilic Aromatic Substitution. Aida 1 Introduction When nitric acid and sulfuric acid are added to benzene, nitrobenzene is produced.
The overall reaction is depicted in Figure 1. James 5 Conclusion: This lab, in my personal opinion, was one of the most successful I
Electrophilic substitution of benzene is the one where an electrophile substitutes the hydrogen atom of benzene. Nitration of Benzene. The nitration of a benzene ring is an electrophilic aromatic substitution reaction, andits general mechanism is summarized in Figure 2. Here nitronium ion (NO 2 +) acts as an electrophile and reacts with benzene to form nitrobenzene.As for example Benzene reacts with concentrated nitric acid in presence of concentrated sulphuric acid as a catalyst, and form nitrobenzene. The electrophile in the nitration of benzene is the + NO 2 (the nitronium ion), which is formed by protonation of HNO 3 by H 2 SO 4 (yep, sulfuric acid is powerful). This reaction proceeds via the formation of an electrophilic nitronium ion (NO 2 + ) from nitric acid (HNO 3 ), … This occurs following the interaction of two strong acids, sulfuric and nitric acid.
