Breaking the covalent bonds in one mole of hydrogen chloride takes about how much more energy than overcoming its intermolecular forces?

1. Intermolecular forces are far weaker than the bonds inside a molecule. 2. Boiling a liquid overcomes only the intermolecular forces, not the covalent bonds. 3. To break the covalent bonds between the hydrogen and chlorine atoms in one mole of hydrogen chloride requires about 25 times more energy, 430 kilojoules. 4. That gap is why boiling a substance does not decompose it. 5. The distinction is between intermolecular and intramolecular forces. _Source: OpenStax Chemistry 2e (CC BY 4.0), Ch 10 'Liquids and Solids', sections 10.1-10.6_
