"Water and ethanol have different molecular structures."
Brief explanation: their different structures give different intermolecular forces. Although both can hydrogen-bond, water forms a stronger, extensive H‑bond network (each molecule can donate two H and accept two lone pairs), so it requires more energy to boil than ethanol (bp 100°C vs 78°C).
