Edexcel IGCSE Chemistry syllabusChemistry 4CH1First assessment 2019

Practise organic-formula questions by completing formula tables, drawing displayed formulae and identifying representation types.

How this is tested

  • Complete formula tables by deriving empirical formulae and relative formula mass.
  • Draw displayed formulae with all bonds shown, including O-H bonds where needed.
  • Classify a representation as empirical, molecular, structural or displayed formula.
