Final answer:
Treatment of a carbonyl compound with water in the presence of an acid or base catalyst can result in hydrolysis to form a carboxylic acid in acidic conditions, or a nucleophilic addition reaction to form a hydrated carbonyl compound in basic conditions.
Step-by-step explanation:
Treatment of a carbonyl compound with water in the presence of an acid or base catalyst can result in various reactions depending on the specific carbonyl compound and catalyst used.
In acidic conditions, the carbonyl group may be hydrolyzed to form a carboxylic acid. The acid catalyst helps facilitate the reaction by donating a proton to the carbonyl oxygen, allowing it to react with water and form a carboxylic acid.
In basic conditions, the carbonyl compound may undergo a nucleophilic addition reaction with water, resulting in the formation of a hydrated carbonyl compound.
