Dehydration of Carboxylic Acids Treatment of a carboxylic acid with an alcohol in the presence of an acid catalyst forms an ester This reaction is called a Fischer esterification The reaction is an equilibrium, so it is driven to the right by exploiting LeChatelier's Principle

Carboxylic acids can be reduced to primary alcohols with LiAlH4 or with BH3 Simple acid anhydrides are named by replacing the ending "acid" with " anhydride" The reaction involves an addition-elimination mechanism, as shown below:
