Bond energies are intramolecular — don't affect bp

The statement is correct. Boiling point is a physical property determined by the strength of intermolecular forces (such as hydrogen bonding, dipole-dipole interactions, and London dispersion forces) that exist between separate molecules. Bond energies, on the other hand, are intramolecular forces that hold individual atoms together within a molecule. When a molecular substance boils, it undergoes a physical change where molecules are separated from one another, but the molecules themselves remain intact. Because covalent chemical bonds are not broken during boiling, intramolecular bond energies do not affect the boiling point of molecular substances.

Boiling point is a physical property determined by the strength of intermolecular forces (the forces of attraction between neighboring molecules, such as hydrogen bonding, dipole-dipole interactions, and London dispersion forces). When a molecular substance boils, it undergoes a phase change from liquid to gas, which requires overcoming these intermolecular forces. The intramolecular covalent bonds holding the individual atoms together within each molecule remain completely intact during this process. Since bond energies measure the strength of these intramolecular bonds, they do not influence the boiling point of molecular substances.

Bond energies describe covalent bond strengths inside molecules, which are intramolecular forces. Boiling point depends solely on intermolecular attractions such as hydrogen bonds and van der Waals forces. Hence the statement is correct: bond energies do not affect bp.

The statement is correct. Bond energies refer to the strength of intramolecular covalent bonds holding atoms together within a molecule. When a molecular substance boils, it undergoes a physical change where intermolecular forces (forces between separate molecules, such as hydrogen bonding or dispersion forces) are overcome. The intramolecular covalent bonds remain completely intact. Therefore, intramolecular bond energies do not affect the boiling point of molecular substances.

Final Summary

The AI Roundtable delivered a masterclass in chemical consensus, with all four models arriving at the same conclusion before a single word of debate was even exchanged. Claude Opus 4.7, GPT-5.5, Grok 4.3, and Gemini 3.5 Flash were unanimous in their verdict: boiling point is strictly a matter of intermolecular forces, leaving internal bond energies entirely out of the equation.

All 4 models agreed on "Yes" after discussion

Strongest Arguments

• Yes: Boiling is a physical change where molecules are separated from one another while remaining intact; because covalent bonds are not broken during this process, intramolecular bond energies have no influence on the boiling point.
