Questions & Step-by-Step Solutions

Which of the following compounds will undergo electrophilic substitution more readily than benzene?
  • Step 1: Understand what electrophilic substitution is. It is a reaction where an electrophile replaces a hydrogen atom in a compound.
  • Step 2: Know that benzene is a stable compound that can undergo electrophilic substitution, but some compounds can do it more easily.
  • Step 3: Identify the compound in question, which is phenol. Phenol has a hydroxyl group (-OH) attached to it.
  • Step 4: Recognize that the hydroxyl group is electron-donating, meaning it helps to increase the electron density in the benzene ring.
  • Step 5: Realize that increased electron density makes the benzene ring more reactive towards electrophiles.
  • Step 6: Conclude that because phenol has the electron-donating hydroxyl group, it will undergo electrophilic substitution more readily than benzene.
