Which outcome limits rotational speed during gas chromatography with large molecules bearing numerous halogen atoms?

💡 Explanation

When large halogenated molecules are in a gas chromatography system, the enhanced electronegativity of halogen atoms greatly increases intermolecular forces dominated by strong dipole-dipole attractions thereby creating more viscous eluents that hinder high speed rotations for separation. Therefore intermolecular dipole attraction limits rotational speed, rather than intramolecular forces, atomic mass, or nuclear charge, those parameters would influence distinct properties.
