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.

The esterification reaction is a five-step reaction. Draw the curly arrow mechanism for the first two steps of this reaction. The steps of the reaction are listed below: Step 1: Acetic acid is protonated by H2SO4. Step 2: The hydroxyl group of the alcohol attacks acetic acid. Step 3: Tautomerism (will be explained in class next semester). Step 4: Water is a good leaving group Step 5: 5% sodium bicarbonate deprotonates the ester to yield the final product.
