Polymers

• What are polymers made up of?

  Smaller units called monomers
• Why are polymers solid at room temperature?

  Due to strong intermolecular forces
• What is the formula for the monomer propene?

  c₃h₆
• How can you identify a polymer molecule?

  By finding the repeating monomer unit
• How would you represent 400 propane monomers in a polymer reaction?

  By drawing the repeating unit with 400
• What do the curved brackets represent in polymer structures?

  Bonds between repeating units
• What type of bonds are present within polymers?

  Covalent bonds
• What must be broken to melt or boil polymers?

  Intermolecular forces between polymer molecules
• How do the melting and boiling points of polymers compare to giant covalent structures?

  Polymers have lower melting and boiling points
• Why do polymers have higher melting and boiling points than simple molecular substances?

  Due to their long chains and many intermolecular forces
• What are the two main types of polymers mentioned?

  • Addition polymers
  • Condensation polymers
