Inorganic Chemistry IV
Crystal Field Theory: Postulates, splitting of dn configurations in octahedral, tetrahedral, tetragonal and square planar fields, spectrochemical series , factors affecting the magnitude of Δ0, crystal field stabilization energy in weak and strong fields; pairing energy, distribution of d-electrons in t2g and eg orbitals in octahedral and tetrahedral complexes, distortion of octahedral complexes, crystal field splitting of d-orbitals in square planar complexes and Jahn Teller theorem; use of CFSE values, number of unpaired electrons and high spin (HS) and low spin (LS) complexes, applications and limitations of CFT.
Types of magnetism, types of magnetic behaviour , orbital and spin magnetic moments, methods of determining magnetic susceptibility by Gouy’s balance, spin only moments of dn ions and their correlation with effective magnetic moments, including orbital contribution; quenching of magnetic moment: super exchange and antiferromagnetic interactions (elementary idea with examples only); applications of magnetic moment data for transition complexes.
Types of electronic transitions; coupling of orbital angular momenta and spin angular momenta (in p2 and d2 configuration), spin orbit coupling/LS coupling, determining the ground state terms – Hund’s rule, hole formulation, calculation of the number of micro states; selection rules- Laporte ‘orbital’ selection rule, spin selection rule, spectroscopic ground states; Orgel energy level diagram for d1-d9 states, (one electron – one hole ), discussion of electronic spectrum of [Ti(H2O)6]+3 complex, charge transfer spectra (elementary idea).
Requirements of gravimetry: properties of precipitates and precipitating regents, particle size and filterability of precipitates, colloidal and crystalline precipitates, co-precipitation and post-precipitation, drying and ignition of precipitates, principles of gravimetric estimation of chloride, phosphate, zinc, iron, aluminum and magnesium singly.
