There are no bond dipoles and no dipole-dipole interactions. Dipole-dipole and dispersion forces must be overcome to boil. For example, the average bond-energy for \(\ce{O-H}\) bonds in water is 463 kJ/mol. \(\ce{CO2}\), \(\ce{CH4}\), and \(\ce{N2}\) are symmetric, and hence they have no permanent dipole moments. 9 0 obj<>
