Organic chemistry

• Combustion 


  Alcohol + Oxygen = Carbon dioxide + water.

  Ethanol + Oxygen = Carbon dioxide + Water
• Reaction with group 1 (alcohols).

  1. What 3 acids react with the group 1 metal?
  2. What is the gas produced by them?
  3. How does the length of carbon chain affect the reaction?

  . Methanol, ethanol, propanol.

  . Hydrogen gas.

  . The shorter the carbon chain the more reactive the alcohol.
• Carboxylic acids.

  1. Alcohols are oxidised they form carboxylic acids.
  2. Each alcohol oxidises.
  3. They turn into: Methanoic, ethanoic, propanoic and butanoic acid.
  4. Their functional group is COOH.
  5. The general formula is: C2H2n+1COOH.
  6. Draw out diagrams and their formula.
• Chemical properties.


  -They all have similar properties as they are all part of the same homologous series.

  -These properties include: flammable, water soluble and being oxidised.

  -They undergo various reactions. You need to know the ones with sodium, air, water and oxygen.
