Hydro carbons

• Alkenes


  • Simplest type of hydrocarbon with general formula CnH2n
• First four alkanes

  • Methane, Ethane, Propane, Butane
• Hydrocarbons are the simplest organic compounds
• The shorter the carbon chain, the more runny a hydrocarbon is, less viscous, more volatile, and more flammable
• Alkanes


  Have all C-C single bonds
• Complete combustion


  Occurs when there's plenty of oxygen, releases lots of energy, waste products are carbon dioxide and water vapour
• Alkanes


  • Homologous series with similar reactions, saturated compounds with each carbon atom forming four single covalent bonds
• Hydrocarbon properties change as the chain gets longer
• Organic chemistry is about compounds that contain carbon
• Properties of hydrocarbons affect how they're used for fuels

  Short chain hydrocarbons with lower boiling points are used as "bottled gases" stored under pressure as liquids in bottles
• Hydrocarbons

  Compounds formed from carbon and hydrogen atoms only
