1. Carboxylic Acids Carboxylic acids contain a carboxyl group: O CH 3 C-O-H ORCH 3 CO 2 H Carboxyl group

2. Reactions of Carboxylic Acids Carboxylic acids can participate in a variety of reactions: – acid-base reactions similar to those of inorganic (without C-C bonds) acids – condensation reactions esterification amidation

3. Reactions of Carboxylic Acids Esterification: – a condensation reaction in which a carboxylic acid reacts with an alcohol to form an ester and water.

4. Saponification of Esters Saponification: – The hydrolysis of an ester in the presence of a base Forms carboxylic acid salt and alcohol
