Paper 2

• Organic chemistry

  Chemistry of compounds containing carbon
• Carbon


  • Useful for making large compounds
  • Can form four strong bonds
  • Most commonly bonded to other carbon atoms or hydrogen atoms
• Hydrocarbons

  Compounds formed from carbon and hydrogen only
• Hydrocarbons

  • Butane
  • Butanol
• Octane has 8 carbon atoms
• Writing balanced combustion equations

  1. Write unbalanced equation

  2. Balance carbon atoms

  3. Balance hydrogen atoms

  4. Balance oxygen atoms
• Propane has the molecular formula C3H8
• Nonane has the molecular formula C9H20
• The key point is that the properties of hydrocarbons like alkanes depend on the length of their carbon chain</b>
