Answer:
Ethanoic acid and 1-butanol can react to produce water and a compound classified as an ester.
Step-by-step explanation:
Ethanoic acid reacts with ethanol in the presence of concentrated sulphuric acid as a catalyst to produce the ester "butyl ethanoate" and water:
CH₃COOH + CH₃CH₂CH₂CH₂OH → CH₃COOCH₂CH₂CH₂CH₃.
