Interpretation Introduction

Interpretation:

The type(s) of intermolecular forces existing in between the molecules of the given compounds have to be identified.

Concept Introduction:

Intermolecular forces are the forces existing between molecules, atoms, ions or dipoles.

Depending upon the type of species involved, the intermolecular forces can be classified as follows:

• Dipole-Dipole interactions.
• Ion-Dipole interactions.
• Dipole-induced dipole interactions.
• Ion-induced dipole interactions.
• Dispersion forces.
• Dipole-Dipole interaction is the interaction between two polar molecules which have net dipole moments.
• Ion-Dipole interaction is the interaction between an ionic species (such as cation or anion) and a polar molecule.
• Dipole-induced dipole is the interaction between an atom (non- polar species) and a polar molecule. In this interaction, a polar molecule induces its dipole moment to a non-polar species which lacks dipole moment.
• Ion-induced dipole interaction is the interaction between an atom (non- polar species) and an ionic species. In this interaction, an ionic species such as cation or anion, induces dipole in a non-polar species which lacks dipole moment.
• Dispersion force is the interaction between non-polar molecules.
