carboxylic acids

• Producing carboxylic acids

  Alcohol + oxygen —> carboxylic acid
• Carboxylic acid functional group and suffix

  -COOH

  -anoic acid
• First 4 carboxylic acids

  Methanoic acid HCOOH

  Ethanoic acid CH3COOH

  Propanoic acid C2H5COOH

  Butanoic acid C3H7COOH
• Carboxylic acids react...

  ...like any other acid eg with carbonates to produce salt, water and carbon dioxide

  The salt will end in -anoate eg

  Ethanoic acid + sodium carbonate —> sodium ethanoate + water + carbon dioxide
• Carboxylic acids in water

  Weak acids in water as they partially dissociate, not all of their molecules release H+ ions/don't ionise completely when dissolving in water.
• Producing esters

  Alcohol + carboxylic acid —> (acid catalyst) ester + water
• Ester functional group

  -COO-
• Ethanol ester

  Ethyl ethanoate
