Final answer:
The attractions holding CCl4 molecules together in the solid state are intermolecular attractions resulting from temporary dipoles, known as London dispersion forces.
Step-by-step explanation:
The attractions between the CCl4 molecules that hold the molecules together in the solid state are best identified as intermolecular attractions resulting from temporary dipoles. This type of intermolecular force is known as London dispersion forces. These are the only type of intermolecular forces present in CCl4 since it is a nonpolar molecule, and thus it does not have permanent dipoles for dipole-dipole interactions or the specific atoms necessary for hydrogen bonding.
