The normal boiling point for H2Se is higher than the normal boiling point for H2S . This can be explained bylarger dipole-dipole forces, larger dispersion forces, and larger hydrogen-bond forces for H2Se .larger hydrogen-bond forces for H2Se .larger dipole-dipole forces for H2Se .larger dispersion forces for H2Se .
