WebThe reaction, called Fischer esterification, is characterized by the combining of an alcohol and an acid (with acid catalysis) to yield an ester plus water. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. WebThe reaction involves the removal of one or more hydrogens (α – hydrogens) from the carbon of C – OH bond. For example, primary alcohols contain two α – hydrogens and can lose one of them to form aldehyde or it can lose both hydrogens to give carboxylic acid. Thus, the presence of α – hydrogen plays an important role.
