CHEM 14B-2: WINTER 2007 Instructor: Dr. LaureORGANIC SOFTWARE & MODELING ASSIGNMENT: ChemDraw and Chem3DCHEM 14B-2: WINTER 2007 Instructor: Dr. Laurence Lavelle CHEMISTRY COURSE ORGANIZATION & SYLLABUS DESCRIPTION: We cover phase changes; thermochemistry; the first, second and third laws of thermodynamics; free energy changes; electrochemistry and its role as energy source; chemical kinetics, catalysis and reaction mechanisms, including organic mechanisms; general classes and naming of organic molecules; functional groups; structure, conformations, and relative energies of organic molecules; application of thermodynamics and kinetics to organic reactions; and the use of molecular modeling software to illustrate molecular structures and their relative energies. Each section will apply fundamental concepts to examples from inorganic and organic chemistry, including reactions that impact the environment. Material covered will also be related to your 14BL lab experiments, in particular your experiments with p-nitrophenylacetate and aspirin. LECTURES: M, W, F 11am in CS 50. You may attend only the lecture you are enrolled in. INSTRUCTOR: Dr. Laurence Lavelle, 3048A Young Hall, Chemistry & Biochemistry, UCLA OFFICE HOURS: M, W, F 2 – 3pm. Brief questions will also be answered after each lecture. Course related information will be available, and your questions can be posted, at any time to Virtual Office Hours (VOH) at http://voh.chem.ucla.edu. All technical problems with VOH must be sent to: [email protected] TA's (Teaching Assistants): To be announced. You may attend only the discussion section you are enrolled in. TA's will arrange their own office hours and these will be posted on VOH. You may go to any and all TA office hours. TEXTBOOK: Chemical Principles Volume 2: The Quest for Insight, 3rd Ed., by Peter Atkins & Loretta Jones. This low priced customized book includes the textbook, study guide, and solutions manual, and is available only at the ASUCLA bookstore. If you desire further supplementary material several other chemistry textbooks have been placed on reserve in College Library. COURSE READER: The Chem 14B course reader includes all course related material, all lecture notes with additional background material, and past exams with solutions. The text and equations are typeset to allow the student sufficient space to write additional class notes. With this low cost bound copy the student should not need any additional notepaper for taking class notes. It is available only at Course Reader Material, 1137 Westwood Blvd. READING & HOMEWORK: Read the assigned chapters. Working through the assigned problems will facilitate your learning the course material and will also develop your problem solving skills. Homework is not turned in or graded. It is your responsibility to do (at least) the assigned homework in order to master the material covered. You should plan for at least 8 hours of independent study per week, and the more problems you do, the more you will learn. ORGANIC SOFTWARE & MODELING ASSIGNMENT: ChemDraw and Chem3D are very useful in learning to draw, visualize and analyze molecules and are the most commonly use software packages used by chemists at universities and in industry. You will be using this software in our computer rooms on the 1st and 4th floors of Young Hall. The organic worksheet assignment is due Friday March 9. QUIZZES & EXAMINATIONS: Two 40min quizzes in discussion section. One 2hr midterm exam. One 3hr final exam. All material is directly related to class notes, readings and homework problems. The best preparation for all of these is to be able to independently work through the assigned homework problems. See VOH for quiz and exam schedule.Special Bonus: The midterm and final will include one homework question taken from your Student's Solutions Manual. All exams must be written in pen. No make-up exams will be given. No one will be permitted to take the final exam either earlier or later than the scheduled time, and no one can receive a passing grade for the course without taking the final exam. There are no regrades. Only non-programmable, non-graphing calculators are allowed. Pagers and cellular phones are not allowed in the classroom during lectures or exams. Students possessing such items during exams or who commit other forms of academic dishonesty will receive a zero on the exam and will be referred to the Dean of Students. GRADING: Quizzes (2 x 40 mins) 80 pts Organic Worksheet Assignment 40 pts One 2hr Midterm (110 mins) 110 pts One 3hr Final (170 mins) 170 ptsTotal 400 pts Each quiz, worksheet, midterm and final has a total score but is not assigned a grade. Only at the end of the quarter when the class average score (out of 400 points) is known are individual and final grades assigned and they are based/curved on the class average. However you need 50% or higher (200 points or higher) to pass this course with a C- or higher. SYLLABUS Thermochemistry and The First Law of Thermodynamics (phase changes; exothermic & endothermic reactions; enthalpy is a state function (Hess's law); using standard enthalpies of known reactions or bond enthalpies or standard enthalpies of formation to calculate an unknown enthalpy; heat capacities; calorimeters; calorimetry calculations; thermodynamic systems; calculating work of expansion and change in energy for a system; the environment and alternative fuels) Ch 6 including Box 6.2 (Omit: 6.11, 6.20, 6.22) Problems: 1, 3, 7, 9, 11, 13, 15, 19, 21, 29, 33, 37, 39, 45, 53, 55, 59, 63, 73, 75, 93, 99, 105, 107 The Second & Third Laws of Thermodynamics (entropy, Boltzmann equation; applying 1st, 2nd & 3rd laws to calculate changes in work, heat, enthalpy, energy & entropy; reversible, irreversible, isothermal & adiabatic changes; temperature dependence of entropy; calculating entropy changes for phase changes & chemical reactions; calculating Gibbs free energy knowing enthalpy & entropy, or equilibrium constant, or free energies of formation; van’t Hoff equation) Ch 7 Problems: 3, 7, 13, 17, 19, 23, 25, 29, 33, 39, 43, 45, 49, 55, 57, 59, 73, 76, 77, 78, 79, 83, 85, 87, 88 Ch 9.3, 9.11 - 9.13 (The rest of Ch 9 was covered in Chem 14A.) Problems: 13, 15, 17, 19, 85, 89, 91, 96, 103, 107, 110, 116 Electrochemistry and its Applications (galvanic/voltaic cells; balancing redox reactions;
