Carboxylic Acid and Ester Reactions

Like all acids, carboxyhc acids react with strong bases via neutralization reactions. For example, propanoic acid reacts with sodium hydroxide to form sodium propanoate and water. 

A carboxylic acid reacts with an alcohol to form an ester via a condensation reaction, a reaction in which two (or more) organic compounds join, often with the loss of water (or some other small molecule). 

An important example of this reaction is the formation of acetylsahcyhc acid (aspirin) from ethanoic acid (acetic acid) and salicylic acid (originally obtained from the bark of the willow tree). 

If we subject a carboxylic acid to high temperatures, it undergoes a condensation reaction with itself to form an acid anhydride (anhydride means without water ). 

Arrange the compounds from least oxidized to most oxidized. O O
