Bonding in Polymers

Cards (13)

  • What are polymers made of?
    Polymers are made by joining together thousands of small identical molecules called monomers.
  • Why are polymers considered very large molecules?
    Because they consist of thousands of monomer units joined together.
  • What is the process of forming a polymer from monomers?
    • Monomers are joined together
    • Thousands of identical monomers combine
    • A polymer is formed
  • What is the name of the polymer formed from ethene?
    The polymer formed from ethene is called polyethene.
  • What type of bond is present between carbon atoms in alkene monomers?
    Alkene monomers have a double covalent bond between the carbon atoms.
  • What type of bond is present between carbon atoms in polymers?
    Polymers have single covalent bonds between the carbon atoms.
  • Why are covalent bonds in polymers considered strong?
    Covalent bonds in polymers are extremely strong, contributing to the stability of the polymer structure.
  • What is a repeating unit in a polymer?
    • Represents the structure of the polymer
    • Shows a single covalent bond between carbon atoms
    • Extends out of brackets on either side
    • Indicates a large number of repeating units with 'n'
  • What do the brackets in the repeating unit of a polymer signify?
    The brackets indicate that the repeating unit extends out in both directions.
  • What does the lowercase 'n' represent in the context of polymers?
    The lowercase 'n' represents a large number of repeating units in the polymer.
  • Why are most polymers solids at room temperature?
    • Intermolecular forces of attraction between polymer molecules are relatively strong
    • Breaking these forces requires a lot of energy
    • High melting point results in solid state at room temperature
  • What are intermolecular forces in the context of polymers?
    Intermolecular forces are the forces of attraction acting between polymer molecules.
  • What is the significance of the strength of intermolecular forces in polymers?
    Strong intermolecular forces result in high melting points, keeping polymers solid at room temperature.
