Questions & Step-by-Step Solutions

What is the IUPAC name of the compound formed when phenol undergoes bromination?
  • Step 1: Understand that phenol is a compound that has a hydroxyl group (-OH) attached to a benzene ring.
  • Step 2: Know that bromination is a chemical reaction where bromine (Br) is added to a compound.
  • Step 3: Recognize that in phenol, bromination can happen at two main positions on the benzene ring: the ortho position (next to the -OH group) and the para position (across from the -OH group).
  • Step 4: Identify the products formed from bromination: 2-bromophenol (ortho) and 4-bromophenol (para).
  • Step 5: Conclude that the IUPAC name for the compound formed when phenol undergoes bromination is 2-bromophenol (if bromination occurs at the ortho position) or 4-bromophenol (if it occurs at the para position).
