4>1 >3 >2 (CH3NH2 >NO2 >N2 >He)
4 has hydrogen bonding, strong intermolecular forces
3 has Dispersion forces
2 has Dispersion forces
1 has Dipole-Dipole forces
Note :greater the molar mass, greater is the Dispersion forces hence N2 >He
Order of intermolecular forces :Hydrogen bond >Dipole-Dipole >Dispersion
