Chem. 130 Organic Chemistry Spring 2016 Schedule number: 20645 Professor Jeffrey Gustafson JGustafson@mail.sdsu.edu COURSE INFORMATION Class Days: MWF Class Times: 11:00-11:50 Class Location: SHW-011 Office Hours: TBD (according to doodle poll on blackboard) Office Hours Location: CSL 208 Course Overview Chem 130 covers the fundamental organic chemistry needed for fields related to health and the environment. Importantly this class will prepare students for Chem 160 (biochemistry), and thus we will spend time on applications of organic chemistry to biochem (after all biochem is just applied organic chemistry). Organic chemistry differs from general chemistry in that it focuses on only a few elements (C, H, N, O, F, Cl, Br, I). The 3-dimensional shape of molecules is particularly important and thus a molecular model kit (sold at book store) is HIGHLY recommended (and will be allowed on exams). We will also discuss fundamental organic transformations and how they care applied to everyday life. Enrollment Information Prerequisites: The prerequisite for Chem 130 is Chem 100. If you have not taken Chem 100 or Chem 200, then you should not be taking this course. (Note: Other college chemistry courses may qualify as a prerequisite. I will consider these and you should see me after the first day of class.) Course Materials Required Text: Essential Organic Chemistry, 3rd Edition, Paula Bruice (ISBN-13: 978-0321593771-1 Optional Model Kit: Prentice Hall Molecular Modeling Kit for Organic Chemistry (or comparable) Electronic Homework: The best way to learn organic chemistry is through doing it. Thus 33% of the classes’ grade (360 points, 30 points per chapter) will be from homework. Unfortunately hand graded homework is not feasible so we have to turn to online homework. We will be using the online homework that comes with the textbook called mastering chemistry. If you go to blackboard and look on the tool panel you will see a link to ‘mastering chemistry’ that will take you to the homework site. Each chapter will have pre- and post-chapter assignments. The Pre-chapter assignments are due the day before we start the chapter. The post-lecture assignments are due a week after we finish the chapter. Lecture Notes: My personal lecture notes will be put up on Blackboard. These notes cover the major topic I will go over, but are not a replacement for coming to class and reading the book!! Worked problems and examples done on the board generally will not be posted. You will miss this material if you don’t attend. Course Structure and Conduct This course will be taught in a traditional lecture ‘chalk talk’ format. It is imperative you start the post-chapter homework as we cover the chapter in lecture. It is also important that you read the book and do the pre-lecture homework before lecture so that you are somewhat familiar with the material as I present it. As there is a large amount of material to be covered, I ask that questions be saved for before class, during my office hours, or after my lecture. The best advice for this class is to be proactive. Start the homework early, come to my office hours if you feel you are falling behind, and read ahead in the book and notes. Course Assessment and Grading Exams: There will be three exams during lecture (150 points each) and one final (250 points). Dates: Exam 1 (chap 1-3): Feb 8th. Exam 2 (chap 4-6): March 7. Exam 3 (chapter 7-9): April 11th. Chapters 11-13 will be represented on the final exam. (note we will not cover chapter 10 in this class). Final Exam: Monday May 9, 1030-1230 in TBD There will be three 1 hour midterm exams during the semester, each worth 150 points. There will be roughly 35 multiple choice questions. The 2 hour final exam is cumulative and is worth 250 points. If beneficial your final exam score can replace your lowest exam score. Because of this there will be no make-up exams. If you miss an exam, for *any reason*, your final exam score will automatically replace it. The final exam is not optional and cannot be dropped. There will be no quizzes. The online homework is worth 360 points. Your final grade will be based on a maximum of 1060 points, distributed as follows: 3 exams (150 points each), 1 Final Exam (250 points), Online Homework (360 points). Letter Grade Assignment: Depending on class performance the Exams may be curved, but never downward. If necessary the class average of each exam will be curved upward to a 72 % (the lowest B-). 90% A 66% C 86% A– 62% C– 82% B+ 58% D+ 78% B 54% D 72% B– 50% D– 70% C+ <50% F Student Learning Outcomes (broken down by chapter…basically the type of questions that will be asked on exams): *****Pre chapter homework is due the day we start the chapter Post Chapter homework is due 7 days after we finish the chapter.

To avoid any delay in the receipt of your accommodations, you should contact Student Disability Services as soon as possible. Please note that accommodations are not retroactive, and that accommodations based upon disability cannot be provided until you have presented your instructor with an accommodation letter from Student Disability Services. Your cooperation is appreciated. Academic Honesty The University adheres to a strict policy regarding cheating and plagiarism. These activities will not be tolerated in this class. Become familiar with the policy (http://www.sa.sdsu.edu/srr/conduct1.html). Any cheating or plagiarism will result in failing this class and a disciplinary review by Student Affairs. Examples of Plagiarism include but are not limited to: Using sources verbatim or paraphrasing without giving proper attribution (this can include phrases, sentences, paragraphs and/or pages of work) Copying and pasting work from an online or offline source directly and calling it your own Using information you find from an online or offline source without giving the author credit Replacing words or phrases from another source and inserting your own words or phrases Submitting a piece of work you did for one class to another class If you have questions on what is plagiarism, please consult the policy (http://www.sa.sdsu.edu/srr/conduct1.html) and this helpful guide from the Library:( http://infodome.sdsu.edu/infolit/exploratorium/Standard_5/plagiarism.pdf) Extra help and tips for Success Help is available in a variety of forms. Work with your classmates on difficult material. Talk to your laboratory TA. Get a tutor. The Chemistry office (GMCS 209) or I can also help you to find one. There will be a review session the Thursday before each exam at 5:00 PM. 10 Musts to get a good grade: Attend all lectures and labs. Read material in book and notes before lecture, prior knowledge will help you become engaged in lecture and better comprehend material. Write questions down, and attend office hours. Do assigned homework (worth more than an exam!). Discuss concepts with classmates, or study partner. Don’t fall behind! Try to see the big picture. Organic chemistry builds upon itself. Many of the topics within a chapter are just a slight variation of something you learned. Be curious. Always ask why? Curiosity makes a scientist tick. Focus on understanding concepts, not memorization. Actively read tests and notes… every few minutes you should try a problem. With Studying it is quality not quantity. Focus on comprehension not memorization.
