Questions & Step-by-Step Solutions

In the nitration of benzene, what is the role of sulfuric acid?
  • Step 1: Understand that nitration of benzene is a chemical reaction where a nitro group (NO2) is added to benzene.
  • Step 2: Know that sulfuric acid (H2SO4) is used in this reaction.
  • Step 3: Recognize that sulfuric acid helps to create the nitronium ion (NO2+), which is the active part that reacts with benzene.
  • Step 4: Learn that the nitronium ion is a strong electrophile, meaning it can attract electrons from benzene.
  • Step 5: Conclude that sulfuric acid is important because it acts as a catalyst, speeding up the reaction without being consumed.
