corresponding to d-d electronic transition appear at 33480 cm$^{-1}$, calculate it's actual lattice energy. (6) The electronic spectra of [FeF$_6$]$^{3-}$ shows one peak corresponding to d-d transition while that of [Fe(CN)$_6$]$^{3-}$ shows more than two peaks. Explain this observation. (4) If the IR spectrum of acetylacetone is compared with that of tris(acetylacetonato)vanadium(III), what is/are the major change one can observe. Explain the observation. (4) The ligand-to-metal charge transfer bands increase in energy in the series: [CoI$_4$]$^{2-}<$ [CoBr$_4$]$^{2-}<$ [CoCl$_4$]$^{2-}$ Explain. [4]
