Questions & Step-by-Step Solutions

Which of the following compounds undergoes electrophilic substitution more readily?
  • Step 1: Understand what electrophilic substitution is. It is a reaction where an electrophile replaces a hydrogen atom in an aromatic compound.
  • Step 2: Identify the compounds in the question. We are comparing toluene and benzene.
  • Step 3: Know the structure of toluene. Toluene has a methyl group (CH3) attached to a benzene ring.
  • Step 4: Understand the role of the methyl group. The methyl group is an electron-donating group, which means it can push electrons towards the benzene ring.
  • Step 5: Recognize the effect of electron donation. The electron-donating effect of the methyl group stabilizes the positive charge (carbocation) that forms during the electrophilic substitution reaction.
  • Step 6: Compare the stability of the carbocation intermediates. Toluene's carbocation is more stable than benzene's because of the methyl group's electron-donating effect.
  • Step 7: Conclude that since toluene's carbocation is more stable, toluene undergoes electrophilic substitution more readily than benzene.
