Ethanol has higher boiling point than ethanol becauseA. ethanol is a polar compound but ethanol is notB. ethanol forms intermolecular hydrogen bond but ethanal does notC. ethanol has higher molecular mass than ethanolD. ethanol forms stronger intermolecular hydrogen bonds than does ethanol

Answer» Correct Answer - B
Both ethanol and ethanol are polar compounds and have comparable molecular masses . The high melting point of ethanol is mainly due to the presence of intermolecular hydrogen bonding between its molecules which is lacking in ethanol.
