Polymers

• What are polymers made up of?

  Monomers
• What is the formula for the monomer propine?

  c$_3$h$_6$
• How can you identify a polymer molecule?

  By finding the repeating monomer unit
• What does the letter 'n' represent in polymer notation?

  The number of repeating units
• How would you represent a reaction combining 400 propane monomers?

  Draw the repeating unit with '400' in the corner
• What type of brackets are used for repeating units in polymers?

  Curved brackets
• What type of bonds are present within polymers?

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

  Intermolecular forces between polymer molecules
• Why do polymers have higher melting points than simple molecular substances?

  They have more intermolecular forces
• What are the two main types of polymers mentioned?

  Addition polymers and condensation polymers
• What are the characteristics of polymers that make them solid at room temperature?

  • Strong covalent bonds within polymers
  • Weaker intermolecular forces between polymer molecules
  • High surface area due to long chains
• What is the difference between melting and boiling points of polymers compared to giant covalent and simple molecular substances?

  • Polymers have lower melting/boiling points than giant covalent structures
  • Polymers have higher melting/boiling points than simple molecular substances
