Question: In the nitration of benzene, which reagent is used to generate the nitronium ion (NO2+)?

Options:

Correct Answer: H2SO4

Solution:

Concentrated sulfuric acid (H2SO4) is used to generate the nitronium ion (NO2+) from nitric acid (HNO3) in the nitration of benzene.

In the nitration of benzene, which reagent is used to generate the nitronium ion (NO2+)?

In the nitration of benzene, which reagent is used to generate the nitronium ion (NO2+)?

Step 1: Understand that nitration of benzene is a chemical reaction where a nitro group (NO2) is added to benzene.
Step 2: Know that the nitronium ion (NO2+) is the active species that will react with benzene.
Step 3: Identify the reagents needed to generate the nitronium ion.
Step 4: Recognize that concentrated sulfuric acid (H2SO4) is used in this process.
Step 5: Learn that concentrated sulfuric acid reacts with nitric acid (HNO3) to produce the nitronium ion (NO2+).
Step 6: Conclude that the combination of concentrated sulfuric acid and nitric acid is essential for the nitration of benzene.

Nitration of Benzene – The process of introducing a nitro group (NO2) into the benzene ring, typically using a mixture of nitric acid and sulfuric acid.
Generation of Nitronium Ion – The formation of the nitronium ion (NO2+) from nitric acid in the presence of concentrated sulfuric acid, which acts as a dehydrating agent.
