base catalysed hydrolysis of ester

One of the advantage of base catalysed hydrolysis is that it is unidirectional .
On the other hand acid catalysed hydrolysis of ester is reversible process.

What is the base hydrolysis of an ester?

Hydrolysis is a most important reaction of esters.
Acidic hydrolysis of an ester gives a carboxylic acid and an alcohol.
Basic hydrolysis of an ester gives a carboxylate salt and an alcohol._{31 jan. 2022}

What is the base hydrolysis?

And from there, we learned that basic hydrolysis is when water acts as an acid to break apart a weak base.
For example, water can react with urea, forming a hydroxide anion, which can then release ammonia from the urea, which is critical for the growth of plants.

What is hydrolysis of ester in basic catalyst?

Ester Hydrolysis with NaOH or base catalysed ester hydrolysis is the reaction of an ester with water under a basic medium.
In it, an ester is heated under reflux with dilute NaOH to yield carboxylate salt and alcohol.

Base-catalyzed hydrolysis of ester occurs by SN2 pathway and is irreversible, because the end product of base-catalyzed hydrolysis of ester produces alcohol and carboxilate ion (not carboxylic acid), which being resonance stabilized shows very little tendency to react with alcohol.
