Alkene and Alcohol reactions

• Alcohols


  Homologous series with OH group
• Alcohols

  • Methanol (1-Carbon)
  • Ethanol (2-Carbon)
  • Propanol (3-Carbon)
  • Butanol (4-Carbon)
• Alcohols with oxygen

  1. Complete combustion

  2. Alcohol + Oxygen → Carbon dioxide + Water
• Alcohols with water


  Dissolve to form a neutral solution
• Alcohols

  • Can be used as fuels
  • Can be used as solvents (in medicine, perfume)
• Functional group c=c


  Allows alkenes to undergo addition reactions where molecules join together to form larger molecules
• Hydration of alkenes


  1. Requires high temperatures and a catalyst

  2. Forms saturated alcohol, functional group OH
• Alkenes don't usually burn with oxygen, causes smokey flames due to incomplete combustion
• Hydrogenation 


  Alkene + Hydrogen -> Alkane
• Hydration

  Alkene + Water -> Alcohol
• Hydrogenation of alkenes 


  Requires a catalyst and forms a saturated alkane functional group (C-C)
