概览
Its ethyl fragment is attached through oxygen, while its acyl fragment comes from ethanoic acid. Acid-catalysed hydrolysis gives ethanol and ethanoic acid reversibly; alkaline hydrolysis gives ethanol and ethanoate before any acid work-up. Product naming requires tracing both sides of the ester link.
