polymers

• What are polymers made up of?


  Polymers are made up of smaller units called monomers.
• What is an example of a polymer mentioned in the material?


  Polypropylene is an example of a polymer mentioned.
• What is the formula for the monomer propine?


  The formula for propine is $C_3H_6$.
• How can you identify a polymer molecule?


  You can identify a polymer molecule by noticing a repeating unit within it.
• What does the letter 'n' represent when drawing polymers?


  The letter 'n' represents the number of repeating units in the overall polymer.
• How would you represent a reaction for combining 400 propane monomers?


  You would draw the repeating unit and put 400 in the corner.
• What type of brackets are used to show repeating units in polymers?


  Curved brackets are used to show repeating units in polymers.
• What type of bonds are present within polymers?


  Polymers contain covalent bonds.
• What needs to be broken to melt or boil polymers?


  The intermolecular forces between separate polymer molecules need to be broken.
• How do the melting and boiling points of polymers compare to giant covalent structures?


  Polymers have lower melting and boiling points than giant covalent structures like diamond.
• How do the melting and boiling points of polymers compare to simple molecular substances?


  Polymers have higher melting and boiling points than simple molecular substances like oxygen.
• Why are polymers generally solid at room temperature?


  Polymers are generally solid at room temperature due to their high surface area and numerous intermolecular forces.
• What are the two main types of polymers mentioned?

  • Addition polymers
  • Condensation polymers
