(a)
Interpretation:
To predict the product of acid-catalyzed hydrolysis of given esters.
Concept introduction:
An acid-catalyzed hydrolysis of the ester is a much faster reaction as compared to uncatalyzed hydrolysis of the ester. The addition of acid protonation of the oxygen atom of the carbonyl group and as it is a fact that an oxygen atom with positive charge has more electron withdrawing tendency than neutral atom. The more withdrawal of electron density decreases the electron density from the carbonyl carbon and make it more susceptible for the attack of the nucleophile. The acid catalyzed reaction mechanism is written as,
Therefore, products obtained by the acid catalyzed ester hydrolysis are the carboxylic acid and an alcohol by which ester was formed.
