Unformatted text preview: Chem 30A, Winter 2006 Prof. Garrell CHEM 30A WEEK'I SYNOPSm GOALS AND ASSIGNMENTS FOR JAN. 9 THROUGH JAN. 13, 2006 MOLECULAR STRUCTURES 8c REACTION ENERGETICS TOPICS: G OALS: Lewis structure recap Formal charges Oxidation and reduction in organic chemistry Reaction energetics: Gibbs free energy change, activation energy , reaction mechanisms Overview of reaction types Representations of molecules, from molecular formulas to three-dimensional visualization Functional groups Bond and molecular dipoles; polarity Lewis structures and resonance Molecular orbital theory recap Refresh your Lewis structure—drawing skills, including assignment of formal charges Be able to recognize oxidation and reduction (Read text pp. 232—235; will not be covered explicitly in lecture, but concept will be used.) Understand the following terms: Gibbs free energy reaction rate exergonic functional group endergonic carbocation exothermic reaction intermediate endothermic rate-determining step potential energy diagram reaction coordinate transition state activation energy(Ea, AGl) reaction mechanism homolytic heterolytic radical Become familiar with the various two- and three-dimensional representations of molecules, and the structural information each reveals. Be able to identify functional groups (Molcular structures synopsis, p. of 2) y 4:7;huwlsrmmwuw" wmmig m w MW‘ V Mara,»me c ,- i s “we ., y,’»t.::‘MiSMkk/WK.<“¢J Maw,» mmm a» w:.~.nwmmm:a la; .mxmmmmymthWM-m ASSEGNMENWS!
