OH H+ CH3 H3C OH Esters can be synthesized by an acid-catalyzed nucleophilic acyl substitution between an alcohol and a carboxylic acid; this process is called the Fischer esterification reaction. Because the alcohol oxygen is a poor nucleophile, the carbonyl carbon is made a better electrophile by protonation of the carbonyl oxygen. The steps of the synthesis are all reversible. The reaction is generally driven to completion by using an excess of the liquid alcohol as a solvent, or by...

H+ R-C-OH + carboxylic acid (excess) R2-OH alcohol + HO Ric-o-R₂ an ester The general reaction scheme for a Fischer esterification is shown above. Using the combination of acetic acid and either isopentanol AND n-propanol you will synthesize two fruity-smelling esters. The hydronium source that will catalyze this reaction is sulfuric...

In the Fischer esterification reaction, a carboxylic acid reacts
with an excess of alcohol in acidic conditions to form an ester.
During the reaction the sp2 hybridized carbonyl carbon of the acid
forms an sp3 hybridized intermediate before returning to sp2
hybridization in the product. Draw the structure of the neutral sp3
hybridized intermediate and the ester product in the reaction
between pentanoic acid and n-propanol.
