Polymers Pt:1

• How long can a single molecule of polypropylene be?

  A single molecule can be thousands of atoms long.
• What is the formula for the monomer propine?

  The formula for propine is C₃H₆.
• How do monomers combine to form polymers?

  Monomers combine by adding together repeatedly to form a polymer chain.
• What is required to break covalent bonds in polymers?

  High temperatures are required to break covalent bonds.
• Why are polymers generally solid at room temperature?

  Because they have strong intermolecular forces that require a lot of energy to break.
• 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.
• What are the two main types of polymers mentioned?

  • Addition polymers
  • Condensation polymers
• What is an example of a polymer mentioned in the video?

  Polypropylene is an example of a polymer mentioned in the video.
• 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.
• What are the two main types of polymers mentioned?

  • Addition polymers
  • Condensation polymers
• How can you identify a repeating unit in a polymer?

  You can identify a repeating unit by picking out a small section that seems to repeat.
• Why are polymers considered a diverse group of substances?

  Because they make up all sorts of different materials.
• Why do polymers have higher melting and boiling points than simple molecular substances?

  Because polymers have a high surface area and many intermolecular forces.
• What is an example of a polymer mentioned in the material?

  Polypropylene.
• What must be broken to melt or boil polymers?

  The intermolecular forces between separate polymer molecules must be broken.
• Why are polymers generally solid at room temperature?

  • Polymers have strong covalent bonds within them.
  • They have many weak intermolecular forces between molecules.
  • The high surface area of long polymer chains contributes to their solid state.
• What is the formula for the monomer propine?

  The formula for propine is $C_3H_6$.
• What notation is used to draw repeating units in polymers?

  Curved brackets are used to draw repeating units.
