Exam points

  • reconstruct an alkene monomer from an addition-polymer repeat unit by restoring the carbon–carbon double bond
  • identify both alkene monomers in a copolymer section by separating its carbon-chain substituent pattern
  • distinguish alkene positional isomers when tracing a substituted polymer chain back to its monomer
