1) a. water molecule breaks up into hydrogen and oxygen on passing electricity. does this involve breaking intermolecular or intramolecular forces of attraction. explain b. on boiling water changes to water vapor. does this involve breaking intermolecular or intramolecular forces of attraction. explain methanol evaporates faster than water. contrast the intermolecular forces and the vapor pressures of methanol and water?
