when a chemical compound breakdown by reacting with water is called hydrolysis.
Hydrolysis occurs when the nucleophile (a nucleus-seeking agent, e.g., water or hydroxyl ion) attacks the carbon of the carbonyl group of the ester or amide. In an aqueous base, hydroxyl ions are better nucleophiles than polar molecules such as water. In acids, the carbonyl group becomes protonated, and this leads to a much easier nucleophilic attack. The products for both hydrolyse are compounds with carboxylic acid groups.

when a chemical compound breakdown by
reacting with water is called hydrolysis.
Hydrolysis & hydrolysis of
ester
when esters are hydrolyzed by water or by dilute
acids such as dilute hydrochloric acid is called
hydrolysis of ester
Base hydrolysis
The type of hydrolysis carried out in the presence of
a base is called base hydrolysis.
Base means; NaOH, KOH.
This reaction is known as “ saponification" because
it is the basis of making soap from glycerol triesters
in fats.
In organic chemistry, acid hydrolysis is a process in
which a protic acid is used as catalyze for motivate a
chemical bond via a nucleophilic substitution
reaction, with the addition of the elements of water
(H2O).
