Water and ethanol have different molecular structures.
Explanation: Their structures determine the strength and extent of intermolecular forces. Water forms a more extensive hydrogen-bonding network (each H2O can hydrogen-bond to multiple neighbors), while ethanol has only one –OH and a nonpolar ethyl group, so its hydrogen bonding is less extensive—giving ethanol a lower boiling point.
