This is the correct statement to explain why water (H2O) and ethanol (C2H5OH) have different boiling points. The difference in their molecular structures leads to different intermolecular forces, which are responsible for the variation in their boiling points. Water molecules are capable of forming strong hydrogen bonds with each other due to the presence of highly electronegative oxygen atoms and hydrogen atoms that are covalently bonded to oxygen. Ethanol also has a hydroxyl group that can form hydrogen bonds, but its additional carbon chain reduces the overall strength of hydrogen bonding when compared to water. The ability of water molecules to form extensive hydrogen bonding networks results in a higher boiling point for water (100°C at 1 atm) compared to ethanol (78.37°C at 1 atm).
