Answer:
Nitrogen gas, which is a nonpolar covalent molecule with dispersion forces.
Step-by-step explanation:
Nitrogen gas is a diatomic gas composed of nonpolar covalent bonds. This implies that the gas particles are held together strictly by weak van der Waals forces.
Van der Waals forces represents the weakest level of intermolecular interaction. They are mostly found in nonpolar substances especially gases. Hence, nitrogen gas will exhibit the weakest degree of inter-particle attraction among all the options listed.
