fischer esterification of lauric acid chegg
Is Fischer esterification a condensation reaction?
An ester is made from a carboxylic acid and an alcohol.
The carboxylic acid and alcohol are heated in the presence of a catalyst, usually concentrated sulphuric acid.
This is a condensation reaction, where two molecules join together to form one larger molecule (the ester) and a small molecule, usually water.What is the mechanism of Fischer esterification reaction?
The Fischer esterification Mechanism can simply be described as – Protonation of the carbonyl, followed by the nucleophilic attack on the carbonyl, the proton transfer to the OH group, the removal of water and finally the deprotonation step.
Esterification Mechanism
Carboxyl oxygen gets protonated to give delocalized carbocation making the carbocation a better electrophile.
A proton is transferred to one of the hydroxyl groups to form a good leaving group.
What is Fischer esterification of lauric acid?
Fischer esterification converts the lauric acid to the ethyl ester of lauric acid in the presence of ethanol and HCl.
The reaction goes as follows: The acid used in the reaction is regenerated at the end of the reaction.
