Alcohols

• The functional group is the part of a molecule that it its characteristic properties
• Alcohols are carbon - based molecules that contain the functional group hydroxyl , - OH
• Methanol , Ethanol , Propanol and Butanol are the first four member of the homologous series of alcohols
• The members of a homologous group all react in a similar way. Why is this?

  They all have the same functional group
• What is the formula of Methanol?

  CH₃OH
• What is the formula of Ethanol?

  CH₃CH₂OH
• What alcohol is shown in the structural formula below?

  Methanol

  
• What alcohol is shown in the structural formula below?

  Ethanol

  
• Alcohols dissolve in water to form neutral solutions
• Alcohols react with sodium to produce hydrogen
• Alcohols burn in air to produce carbon dioxide and water
• Alcohols are used as fuels and solvents
• Alcoholic drinks contain ethanol
• Ethanol can be oxidised to ethanoic acid by chemical oxidising agents or by the action of bacteria from the air
• Ethanoic acid is the main acid in vinegar
