Interpretation Introduction

Interpretation:

The kind of intermolecular forcespresent between benzene moleculesis to be identified from the given forces.

Dispersion forces

Dipole–dipole forces

Hydrogen bonding

Ion–dipole interactions

Ionic bonding

Concept introduction:

The various kinds of interactions that bind a molecule or the attractive forces that hold particle together in the condensed phases are known as intermolecular forces. They can be dispersion, dipole–dipole, ion–dipole, and hydrogen bonding.

Dispersion forcesare weakattractive forcesthat are generated by the positions of electrons in two adjacent atoms (or by movement of electrons in nonpolar molecules) by which temporary dipoles are created.

Dipole–dipole interactions are attractive forces that act between polar molecules.

Hydrogen bonding is a type of dipole–dipole interaction. It occurs only in molecules that contain hydrogen atom that is attached to highly electronegative atom such as N, O, and F.
