  C$n$H$2n+$$2$
• What does an empirical formula represent?

  The simplest whole number ratio of atoms
• What is the empirical formula for butan-1-ol?

  CH$2$O
• What does a molecular formula indicate?

  The actual number of atoms in a molecule
• What is the molecular formula of butan-1-ol?

  C$4$H$10$O
• What does a structural formula illustrate?

  How atoms are arranged and bonded

  Showing the precise arrangement of atoms
• What are the different types of formulae used to represent organic compounds?

  • General formula
  • Empirical formula
  • Molecular formula
  • Structural formula
  • Skeletal formula
  • Displayed formula
• What is the purpose of a displayed formula?

  To show all atoms and bonds precisely
