    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)
