Concept explainers
(a)
Interpretation: The main intermolecular force of given liquid chromatography solvents has to be explained.
Concept Introduction: The London dispersion force is the weakest intermolecular force. When the electrons in two adjacent atoms live in positions to make the atoms structure temporary dipoles. This force is occasionally called induced dipole-induced dipole magnetism.
A dipole-dipole interaction is the desirability among two polar molecules
A hydrogen bond is an electrostatic attraction between two polar groups that occurs when a Hydrogen atom, covalently bound to a highly electronegative atom such as Nitrogen, Fluorine, and Oxygen.
