2 Learning Outcomes Gain an intensive introduction to organic chemistry as a solid foundation for subsequent study in chemical, biological and materials sciences. Learn a set of important tools and concepts that enable appreciation and powerful application of modern organic chemistry. Academic integrity Each student in Chem 3590 is expected to abide by the University s Code of Academic Integrity. Please familiarize yourself with the Code, which is posted on the University s website: Diversity & Inclusive Excellence Chem 3590 is open to the views of each and every student in the classroom. Please honor the uniqueness of your fellow classmates and appreciate the opportunity to be in an environment where we can all learn from each other. Responsibility to Notify All students are expected to promptly notify the TA of any issues that may interfere with the performance and participation in all course-related matters. 2

4 Molecular Models (come with the Text above) These models are indispensable for understanding stereochemical problems in organic chemistry that often define fundamental properties of materials, biomolecules and drugs. You are allowed to bring the model kit to the exam. Web Site The course web site is Piazza linked through blackboard. The web site will contain all materials handed out in class, as well as problem sets, exams, and their solutions. We will also post copies of hand-written notes and power point slides from all lectures and review sessions, and all handouts given out in individual sections. The site also contains recent chemistry news, and digital chemistry animations expressing various key concepts. Studying Throughout the semester, we will be discussing a large amount of difficult material in a short amount of time. It is critical that you do not fall behind in your studies. Often, understanding of new material in organic chemistry relies upon mastery of ideas previously discussed. We urge you to review your class notes immediately after class and to clear up ambiguities while the subject is still fresh in your mind. An important component of your study will be the practice problems from the recommended, a copy of which will be posted on Piazza. It is often said that you cannot study organic chemistry without a pencil in your hand. Please make the effort to use these problems in your study and consult the solutions only after you have worked out your own answers. 4

5 TA office hours Office hours will begin the 2nd week. See page 1 for time/day and location. The final time/day selected was based on the class votes. Regular attendance at section is strongly encouraged. In order to get the most out of your office hours, always review the material before coming to office hours. Homework There will be 9 assigned problem sets over the course of the semester. 1 or 2 questions will be arbitrarily picked from each PSet and graded. These grades will make up of the entire class. Problem sets will be will be made available on Piazza. Problem sets will be due precisely on the dates/times listed on the PSet. Answer key will be posted on the course web site 24 hours after the due date. "late" hand-ins will receive only 50% of the credit they would have received had they been on time. No credit will be given to the Psets handed in after answer key has been posted. They will not be graded either. Some of the homework problems will be difficult, and you are advised not to wait until the last moment to begin working on your assignments. Although working with classmates on homework sets is encouraged, it is to your own benefit to make an effort on each problem before collaborating with others. Copying another student's solutions will not be tolerated. Prelims Three written exams will be given during the course of the semester (dates above). Material discussed in the lecture immediately preceding the exam will not be covered on the exam (see course syllabus). Use of molecular models will be permitted. Exams 2 and 3 will be comprehensive. Although emphasis will be placed on recent material, knowledge of any topic previously discussed is expected. The final exam is also comprehensive (date and time: TBA). No make up exams will be administered. In the event of a missed exam, the lowest hour exam score will be replaced with the final exam score. For all students, the final exam score will automatically replace the lowest hour exam score, if this is advantageous in the calculation of the course grade (see Grades). 5

6 Regrades You will have one week from the day a graded homework or exam is returned to request a regrade. Homework regrades should be submitted directly to your TA (not to the instructor). Requests for exam regrades should be given to the TA with a brief note attached explaining the problem. Please note, students submitting an exam for regrade will necessarily submit the entire exam for regrading. Grades Grades will be determined based on the total numeric score. You will be allowed to drop either your lowest hourly exam or half of your final exam, whichever is to your advantage. These two options are delineated below; the more advantageous option will be determined and applied automatically. Option 2* Option 1 Exam 1 Exam 2 Exam 3 Homework Final Best Exam 2nd Best Exam Homework Final 40% Total 100% Total 100% *Option 2 applies automatically in the event of a missed hourly exam. Ways to gain bonus points (up to 30%) (1) In-class quizzes and breakout sessions ( (up to ) (see next page) Think-Pair-Solve (2) End-of-semester flash talks and games (more information: TBA) (up to 10%) (Peer evaluated) 6

7 You MUST register for Learning Catalytics. Registration is FREE: Before the first lecture, register for a student account at Learning Catalytics using access code: USLCSX-TRAIL-POIND-SPINA-TAROT-PULSE Do not pay with a credit card! This is a free trial graciously provided by Pearson Education. If possible, bring a web-enabled device to each lecture, such as a smart phone, ipod Touch, tablet, or laptop. Smaller is better, so you don't need a laptop if you have a smart phone or ipod Touch. 7
