Alkanes (Hydrocarbons)


  • Alkanes are chains of carbon atoms surrounded by hydrogen atoms
  • Alkanes only contain ONE covalent bond
  • Examples of Alkanes include Methane, Ethane, Propane and Butane
  • Alkanes burn to give Carbon Dioxide and Water

Alkane+Oxygen -> Carbon Dioxide + Water

  • Alkanes are almost completely unreactive because of their C-C and C-H bonds

  • Alcohols are soluble in water
  • Alcohols have a lower boiling point thanwater and alkanes
  • Alcohols evaporates easily, releasing fumes which are highly flammable
