{"knowledge_schema": {"broad_category": "Chemistry \u2192 Organic Reactions \u2192 Hydrolysis", "refinement": "This reaction involves the hydrolysis of an ester (ethyl acetate) to produce an alcohol (ethanol) and a carboxylic acid (acetic acid).", "specific_scope": "The focus is on identifying the appropriate reagent that facilitates the hydrolysis of ethyl acetate under basic conditions.", "goal": "Select the correct reagent that will effectively convert ethyl acetate into ethanol and acetic acid through hydrolysis."}, "summary": "The problem involves identifying the suitable reagent for the hydrolysis of ethyl acetate into ethanol and acetic acid. The correct choice is NaOH (aqueous), which provides the necessary basic conditions for the hydrolysis reaction to occur. Other candidates like concentrated H2SO4, NaCN, and dilute HCl do not facilitate this specific transformation effectively."}
