The Carbonyl Group, Part V: Carboxylates–Coming Clean
Brian C. Smith
Carboxylates are made by reacting carboxylic acids with strong bases such as inorganic hydroxides. Carboxylates contain two unique carbon–oxygen "bond and half" linkages that coordinate with a metal ion to give two strong infrared peaks, which make them easy to see.
