Structure and Reactivity Chapter 2 Sections: 0, 1, 2, Table 2, 3, Table 3, 4, Table 5, Table 6, [ Nomenclature : Be sure that you can draw the correct structure from a molecule's name. For 140A you need not learn how to provide the correct name from a structure], 6, 7, 8 Exercises: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10ab, 11, 13, 14, 15, 16ab, 17, 18, 19, 20, 21, 22abc, 23 Problems: 26, 27(not iii), 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 45, 46b, 47, 48, 49, 52, 53, 54, 55, 56 TAKE HOME: The structure of a molecule determines its reactivity and we can begin to predict what reactions will occur if we understand functional groups and molecular conformation.

Kinetics and Thermodynamics Thermodynamics – The energy involved and the extent to which a reaction between reactants proceeds to products Kinetics – The rate at which the concentration of products and reactants change. Reaction velocity, or speed. When the reactants and products concentrations no longer change, the reaction is at equilibrium. Gibbs standard free energy change, Δ G o = -RTlnK Gas Constant R = 1.986 cal K -1 mol -1 T = Temperature in Kelvin (K) K = Equilibrium Constant

Enthalpy and Entropy Enthalpy: The heat of a process at constant pressure Depends on the change in energy associated with bond strengths. For a reaction the enthalpy change will be related to the sum of bond strength energies across the reaction. Entropy: A measure of the disorder of a system.
