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 pentanioc acid and n-propanol.
Which reactant provides the oxygen atom found in the ester linkage: Pentanoic acid, or propanol?
Homework Answers
The Fischer esterification is an organic reaction used to condense a carboxylic acid and an alcohol in order to form an ester using an acid as catalyst. Thus, it is also called an acid-catalyzed esterification.
Fischer esterification involves the reaction of carboxylic group with alcoholic group to form an ester along with dehydration in the presence of an acid catalyst.
The mechanism of the Fischer esterification reaction for pentanoic acid and n-propanol is given below:
The oxygen present in the ester linkage is provided by propanol.
Ans:The structures of the 
hybridized intermediate and the ester product are as follows:

Esterification is the reaction of a carboxylic acid (RCOOH) with an alcohol (R'OH) to form an ester (RCOOR') with loss of water. Equation [1] is an example of an intermolecular esterification reaction. Equation [2] is an example of an intramolecular esterification reaction, that is, the carboxylic acid and alcohol are contained in the same starting material, forming a cyclic ester as product. The equilibrium constants for both reactions are given. Explain why K is different for these two apparently similar...

This is a Fischer Esterification using the alcohol, methanol,
and the carboxylic acid, butyric acid, to create the ester, methyl
butanoate (smells like apple). After refluxing methanol, butyric
acid, and concentrated sulfuric acid, a separatory flask was used
and the ester was extracted using ice water, then diethyl ether,
then 2 portions of sodium carbonate, and a saturated sodium
chloride brine solution. Anyhydrous sodium sulfate was used after
separation to dry the ester. Please help!!
