Questions & Step-by-Step Solutions

What is the repeating unit in the polymer polystyrene?
  • Step 1: Understand that a polymer is made up of many small units called monomers.
  • Step 2: Identify the monomer for polystyrene, which is styrene.
  • Step 3: Know the chemical formula for styrene, which is C8H8.
  • Step 4: Realize that when styrene molecules link together, they form the polymer polystyrene.
  • Step 5: The repeating unit in the polymer is the part of the styrene molecule that repeats, which is C8H8.
