    1. Inorganic Chemistry – An Overview Nestor S. Valera Department of Chemistry Ateneo de Manila University

    2. Inorganic Chemistry … Originally meant “nonliving chemistry”. Now includes other subjects e.g. structure, reactivity, catalysis, stability, symmetry, experimental techniques; gas-phase, solution, and solid-state chemistry; superconductors, clusters, coordination compounds, bioinorganic molecules, etc.

    3. Why do we study inorganic chemistry? To fine-tune chemistry concepts learned during earlier formative years. To provide tools to assist the student in rationalizing structure and reactivity. To report the discovery of novel compounds and/or synthetic processes.

    4. Organic vs. Inorganic Compounds

    5. Organic and Inorganic Molecules

    6. Terminal and Bridging Groups

    7. Metal-metal bonds

    8. Sigma-, Pi-, and Delta-bonds

    9. Crystal Field Theory

    10. MO Diagrams of ML6 (sigma only)

    11. Classes of Inorganic Reactions acid-base addition elimination oxidation-reduction insertion substitution rearrangement metathesis solvolysis chelation cyclizationn and condensation nuclear reactions

    12. Chemical Equilibrium for any chemical reaction aA + bB + cC +... = kK + lL + mM

    13. The Reaction Free Energy G = H - TS ?G = ?H – T?S (at constant temperature) ?rG = S?fG(products) - S?fG(reactants) ?rG = -RT ln K Spontaneous Process: ?rG < 0

    14. Kinetics Provides insight into the mechanism of a reaction. A kinetic study begins with the determination of the empirical rate law. The rate of a reaction may be modified by the use of a catalyst.

    15. A “Spontaneous” Process... ?rG < 0 (sufficiently negative reaction free energy) The rate of the reaction is appreciable.

    16. Chemistry is Not a Fragmented Discipline... acid/base chemistry, organometallics (with organic chemistry) redox, spectra, solubility (with analytical chemistry) structure, spectra, theory (with physical chemistry) organometallic catalysts (with polymer chemistry) coordination compounds (with biochemistry)
