SUMMARY
The compounds C2Br6, C2F6, C2I6, and C2Cl6 are arranged in order of increasing boiling points as follows: C2Cl6 < C2Br6 < C2I6 < C2F6. C2F6 has the highest boiling point due to the presence of dipole-dipole interactions, which are stronger than the London dispersion forces present in the other compounds. The boiling points also correlate with molar mass, where heavier compounds require more energy to break intermolecular forces. The discussion highlights the importance of molecular geometry and electronegativity in determining boiling points.
