N2 is non-polar molecules, NO2 is polar molecules that have slightly positive charge on N and slightly negative on O, so intermolecular forces are stronger in NO2
Answer: The intermolecular forces "Dipole-dipole forces" in NO2 is more stronger than "London-dispersion forces" in N2.
Explanation:
Dipole-dipole forces is considered as an attractive force (5.0 kJ to 20.0 kJ) of the positive end of one polar molecule with the negative end of another polar molecule and it is found in NO2.
The London dispersion force is the weakest intermolecular forces. It results when the electrons in two neighboring atoms positions that make the atoms form temporary dipoles and it is found in N2. This force is sometimes called an induced dipole attraction.
So, The dipole-dipole forces are more stronger than that of London-dispersion forces.
