Differences in alkane and alkenes

• Similarities in structure

  Both hydrocarbons

  Both contain carbon and hydrogen atoms

  Both covalent bonds

  Both small molecules
• Differences in structure

  Alkane is saturated

  Alkene in unsaturated
• Similarities is reactions

  Both react with oxygen in complete combustion

  To produce carbon dioxide and water

  Both react with oxygen in incomplete combustion to produce carbon , carbon monoxide and water
• Differences in reactions

  Alkene decollurizses bromine water alkane doesn't

  Incomplete combustion is more likely with Alkene

  Alkene is more reactive

  Alkene reacts with water to make an alcohol

  Alkene react with halogens to make halogenoalkenes

  Alkene can polymerise
