polymers

• give types of polymerisation

  addition and condensation
• describe addition polymerisation


  alkenes form polymers by opening up double carbon bond
• describe condensation polymerisation


  monomers bond to form polymer and small molecule
• give conditions of condensation polymerisation

  • each monomer have at least two functional groups
  • at least two different functional groups across monomers
• give types of naturally occurring polymers

  • polypeptide
  • dna
  • carbohydrates
• describe polypeptide polymer 


  monomers of amino acids with amino group and carboxylic group react by condensation polymerisation
• describe dna polymer 


  two polymer chains of nucleotide monomers
• describe carbohydrate polymers 


  starch, cellulose and glycogen formed from glucose and fructose
