KVV E-Modules - Nitration of Benzene

Quadrant -I (Video)

Nitration of Benzene video

This video lecture explains the nitration reaction of benzene. The video begins by introducing nitration as a fundamental example of electrophilic aromatic substitution (EAS), a key reaction in aromatic chemistry. …

1. Assignment on Nitration of Benzene

In your own words explain or discuss, What is the role of the electrophile in the nitration of benzene, and how is it generated? Which step in the nitration mechanism do you think is the most critical or interesting? Explain why. How does the stability of the benzene ring affect the overall reaction mechanism of electrophilic substitution?

Quadrant - IV (MCQs)

Benzene ring is....

A: electron rich B: electron deficient C: with multiple covalent bonds D: ionic in nature

Benzene reacts with .....

A: electron rich species B: electron deficient species C: negatively charged ions D: neutral species

Generation of electrophile may takes place by

A: acid catalyzed dissociation B: spontaneous dissociation C: both a & b D: Lewis base

True or False: sigma-complex is resonance stabilized carbonium ion produced by attack of electrophile.

A: True B: False C: Can not be told

In nitration of benzene, the electrophile generated is...

A: NO2 B: (NO2)+ C: (NO2)- D: NO

What is the role of concentrated sulfuric acid in the nitration reaction?

A: Catalyst and dehydrating agent B: Oxidizing agent C: Reducing agent D: Source of benzene

What temperature range is typically maintained during the nitration of benzene to prevent multiple nitration?

A: 0–10°C B: 20–25°C C: 50–55°C D: 80–100°C

Why is nitration of benzene considered a substitution and not an addition reaction?

A: Benzene ring is unstable B: Addition is slower C: Substitution retains aromatic stability D: Nitration always forms two products

What is the effect of using excess nitric acid and higher temperature in the nitration of benzene?

A: Only mono-nitration occurs B: Reaction stops completely C: Benzene evaporates D: Formation of di- and tri-nitrobenzene
