The attraction which exists between carbon diozide molecules in solid carbon dioxide is due to

Van der waal's force of attraction

Explanation:

Van der waal's force of attraction

Forces of Van der Waals involve attraction and repulsion among atoms, particles, and surfaces as well as many other intermolecular forces. These vary from covalent and ionic bonding in that they are caused by similarities in surrounding particle fluctuating polarizations (a result of quantum dynamics).
