The 20 questions

  1. What is an addition polymer?

    • A polymer formed by joining alkene monomers across their C=C double bonds
    • A polymer made from amino acids only
    • A polymer formed by ionic bonding between metal ions
    • A polymer formed by condensation with loss of water

  2. What is the repeating unit of poly(ethene) made from ethene?

    • -CH=CH-
    • -C2H6-
    • -CH2-CH2-
    • -CH2-CH3

  3. What is the monomer for poly(chloroethene), PVC?

    • Chloromethane, CH3Cl
    • Chloroethane, CH3CH2Cl
    • Dichloroethene, CHCl=CHCl
    • Chloroethene, CH2=CHCl

    • Poly(chloroethene)
    • Poly(phenylethene), also called polystyrene
    • Poly(ethene)

  5. Which feature of PVC is changed by adding a plasticiser?

    • Its colour only
    • Its molar mass
    • Its flexibility and softness
    • Its chemical formula

  6. Why are addition polymers unreactive?

    • They contain ionic bonds that break easily
    • They have strong C-C and C-H bonds and no reactive functional groups
    • They are unreactive because they are always liquids
    • They contain many C=C double bonds that are reactive

  7. What type of intermolecular forces are present between molecules of polyalkenes?

    • Van der Waals forces (London forces)
    • Hydrogen bonds only
    • Metallic bonds
    • Ionic bonds

  8. Which structure is the repeating unit of poly(propene)?

    • -CH2-CH2-CH2-
    • -CH2-CH(CH3)-
    • -CH=CH-CH3-
    • -CH(CH3)2-

  9. Which monomer gives the repeating unit -CH2-CHCl- in an addition polymer?

    • Chloroethene
    • Ethene
    • Trichloroethane
    • Chloroethane

  10. What is the empirical formula of the repeating unit of poly(ethene)?

    • C4H8
    • C2H4
    • CH2
    • C2H6

  11. What is the molecular formula of the monomer that gives the repeating unit -CH2-CH(C6H5)-?

    • C8H8
    • C8H10
    • C7H8
    • C6H6

    • Tetrachloroethene, CCl2=CCl2
    • Fluoroethane, CH3CH2F
    • Trifluoromethane, CHF3
    • Tetrafluoroethene, CF2=CF2

  13. Which statement correctly describes how to draw the repeating unit from a section of a polymer chain?

    • Remove the end groups and show the repeating unit between brackets with the n subscript
    • Replace all hydrogens with chlorines
    • Draw only the end groups of the chain
    • Add an extra carbon to each unit

  14. What is the structure of the monomer from a section of poly(chloroethene), -CH2-CHCl-CH2-CHCl-?

    • CH2=CH2
    • CHCl=CHCl
    • CH2=CHCl
    • CH3CH2Cl

  15. Why does the polymer chain of an addition polymer contain only single bonds in the backbone?

    • Each C=C bond in the monomers opens to form a single bond in the backbone
    • The backbone is always aromatic
    • Addition polymers contain only ionic bonds
    • Each monomer loses a C=C bond to become a radical

  16. Which feature makes polymers such as poly(ethene) useful for packaging?

    • They are flexible, tough and unreactive
    • They contain radioactive atoms
    • They are ionic and conduct electricity
    • They are very reactive and dissolve easily

  17. What is the IUPAC-style name of the polymer from chloroethene?

    • Chloropolyethene only
    • Polyethenechloride
    • Poly(chloroethene)
    • Polychloroethane

  18. What is the name of the polymer made from propene in IUPAC-style naming?

    • Poly(propane)
    • Polypropyl
    • Polypropanol
    • Poly(propene)

  19. Explain why addition polymers made from alkenes are considered commercially important.

    • They are only used as ionic conductors
    • They are used only as fuels because they are very reactive
    • They are formed only in the laboratory and never industrially
    • They have many uses in modern society and their properties can be modified with additives such as plasticisers

  20. Explain why the knowledge of polymer production has developed over time.

    • Polymers were always made in the same way with no changes
    • No research was needed because polymers form naturally with no control
    • Polymers were discovered only recently in space
    • Research on monomers, catalysts and polymer properties has led to improved materials and processes
