Ion-dipole intermolecular forces of attraction is present between a sodium cation and chloromethane molecule.
The different types of intermolecular forces of attraction are London dispersion forces (LDF), ion-ion, ion-dipole, dipole-dipole, and hydrogen bonding. Molecules could have a mixture of these kinds of intermolecular forces.
Chloromethane, CH3Cl, is considered to be slightly polar due to the carbon-chlorine bond, wherein the chlorine is slightly negative due to its higher electronegativity compared to carbon. With this, the dominant intermolecular forces between CH3Cl are dipole-dipole forces. If a sodium cation is added to the solution, then there would be ion-dipole intermolecular forces of attraction.
