7.6 Hydrolysis of Amides. The reversibility of this reaction means that an amide can hydrolyze to form an amine and a carboxylic acid.

Is acid hydrolysis of amide reversible?
The reversibility of this reaction means that an amide can hydrolyze to form an amine and a carboxylic acid. This reaction is reversible exergonic.
Why is acid catalyzed amide hydrolysis irreversible?
Acid-catalysed hydrolysis reactions are reversible. The forward reaction is driven over to product by using an excess of water, usually as the solvent. Base-mediated hydrolyses, however are essentially irreversible because the product is a non-electrophilic carboxylate salt.
Is acid catalyzed hydrolysis reversible?
Acid-catalyzed hydrolysis of ester is reversible and occurs by SN1 pathway. Acid catalysts speed up the reaction by protonating carbonyl oxygen and thus rendering carbonyl carbon more susceptible to nucleophilic attack.
Hydrolysis is a reversible reaction, meaning that the alcohol and acid groups can react with each other to produce a polyester bond and water as a by-product.
