Ndicate the kinds of intermolecular forces that would occur between the toluene and hexane:

The kind of intermolecular forces that occur between the toluene and hexane are dispersion forces. Toluene is non polar compound that would dissolve in hexane. These dispersion forces are weak and also called as induced dipole-induced dipole attraction. This form a partially charged that too temporary and this dipole - ions have a short-lived communication.
