Carboxylic acids and esters - Summary

  • carboxylic acids
  • esters
HideShow resource information

  • The carboxylic acid functional group is -COOH. They are found naturally in many foods. Naming: the '-e' is replaced with '-oic acid'.
  • They may be made by oxidation of primary alcohols.
  • They readily form salts with many metals, alkalis, bases & carbonates.
  • Esters are formed when carboxylic acids (or acid anhydrides) react with alcohols. A water molecule is also formed in the reaction.
  • Esters of aliphatic alcohols have fruity smells. Fats & oils are esters of glycerol & long chain carboxylic acids.
  • Esters are hydrolysed to form alcohols & carboxylic acids by warming the ester with an acid catalyst. Warming an ester with an alkali breaks it down to form an alcohol & a carboxylic acid salt.
  • Esters are used as flavours & fragrances, as well as in the renewable fuel (bio diesel).
  • The ester functional group is:
