Description: | Aims: To revise some basic concepts in physical organic chemistry and develop a number of ideas used to correlate reactivity and mechanism in a range of organic reactions. Learning Outcomes: After studying the Unit, students should be able to: * Describe some experimental tools for investigating reaction mechanisms and the use of some theoretical models for their correlation and interpretation * Suggest solutions for complex problems involving combinations of numerical and mechanistic information from a variety of sources. * Propose appropriate experimental approaches for determination of organic reaction mechanisms. Skills: Problem solving (T, F, A), Scientific writing (F, A), Independent working (F). Content: Energy changes in equilibria and reactivity. Transition states and saddle points. Activation parameters. Analysis of reaction coordinates. Principle of Least Nuclear Motion. Hammond Postulate. More O'Ferrall - Jencks diagrams. Rate - equilibrium correlations. Hammett equation as an example of a linear free-energy relationship. Significance of s and rfor reactivity and mechanism. Complex Hammett plots: change in mechanism vs. change in rate-determining step. Equilibrium and kinetic isotope effects. Primary and secondary effects and their significance. Heavy-atom effects. Solvent isotope effects. |
