Calculate the energy of a photon emitted when an electron in a hydrogen atom undergoes a transition from n=3 to n=1? Please help and show all steps.
The dipole moment of hydrogen chloride is 1.08D while that of hydrogen bromide is 0.82D. On the basis of dipole-dipole interactions, hydrogen chloride should have a higher boiling point than hydrogen bromide. The opposite is the case, however. Why
