Acidic hydrolysis of an ester gives a carboxylic acid and an alcohol. Basic hydrolysis (saponification) of an ester gives a carboxylate salt and an alcohol. The hydrolysis of an amide produces a carboxylic acid and ammonia or an amine.
WebAs expected, when nitriles are hydrolyzed (by nucleophilic addition of water followed by nucleophile elimination), they form either carboxylic acids or amides, depending on the conditions. General reaction Water is used along with the acid, to provide the reagent for the hydrolysis. Example WebThe carboxylic acid group is the most common type of acidic group found in drugs.
