N2 is a linear molecule represented by two nitrogen atoms held together by a triple bond. Since this bond is non-polar, the only force present is the London Dispersion force.
Dispersion forces and dipole -dipole interactions (toluene has a small permanent dipole moment.)
Because N2 molecules are nonpolar, the intermolecular forces between them are dispersion forces, also called London forces.

N2 would have the lowest BP because it has the weakest intermolecular forces.
It's to do with the intermolecular bonds (the van Der Waals forces). If they are strong, the substance exists as a solid as the particles are held together with a strong force. If however they are weak, the substance will be a gas.
NO2 has a higher boiling point than CO2 because the nitrogen radii is larger than carbon. The bigger the atom the more intermolecular force that is created...this requires more energy to break causing a higher boiling point.
O2, because it have more electrons than N2
In liquid ammonia one hydrogen atom from an adjacent molecule can form an intermolecular hydrogen bond with the nitrogen atom of the central ammonia molecule. With an average of only one intermolecular bond per ammonia molecule, less thermal energy is required to break the liquid ammonia into individual gas phase molecules. Therefore a lower boiling temperature results. In the case of liquid water, one hydrogen atom from each of two adjacent water molecules can form an intermolecular hydrogen bond with each lone pair on the oxygen atom of the central water molecule. As such, a greater amount of thermal energy is required to break the extensive hydrogen bonding network and a higher boiling temperature results.
N2 has dispersion forces and covalent interactions between the two atoms due to the triple bond in it.

In vanderwaal's Equation 'a' measures the intermolecular force of attraction and 'b' measures the volume of the molecule. N2 has greater volume (due to it's larger size) and hence 'b' is greater for N2. NH3 has greater dipole moment and hence 'a' is greater for NH3.
