Chapter 11: Polymers (chem)

• What process is used to make polymers from alkenes?

  Addition polymerisation
• What are the products of addition polymerisation?

  Very large molecules called polymers
• What is the repeat unit in a polymer?

  It has the same atoms as the monomer
• How should you represent a polymer when drawing it?

  Draw bonds coming off the C's and include 'n'
• What is condensation polymerisation?

  • Involves monomers with two functional groups
  • Monomers join together, losing small molecules (e.g., water)
  • Produces simplest polymers from two different monomers
• What is produced when monomers react in condensation polymerisation?

  Small molecules such as water
• What do amino acids contain in their structure?

  An amine group and a carboxylic acid group
• What do amino acids produce when they react by condensation polymerisation?

  Polypeptides
• How can different amino acids be combined?

  In the same chain to produce proteins
• What is the role of DNA in living organisms?

  • Encodes genetic instructions
  • Essential for development and functioning
  • Composed of two polymer chains
• What are the monomers that make up DNA?

  Nucleotides
• What structure do DNA molecules form?

  A double helix
• What are other naturally occurring polymers important for life?

  • Proteins (monomer: amino acid)
  • Starch (monomer: glucose)
  • Cellulose (monomer: glucose)
• What is the monomer of proteins?

  Amino acid
• What is the monomer of starch?

  Glucose
• What is the monomer of cellulose?

  Glucose
