Practise drawing and naming methanol, ethanol, propan-1-ol and butan-1-ol from structural formulae, displayed formulae and tables.

How this is tested

  • draw displayed formulae for alcohols with every bond shown, including O-H
  • name methanol, ethanol, propan-1-ol and butan-1-ol from structural formulae
  • complete alcohol tables using structural formulae and relative formula masses
