Chem 241 Fall 2010 1 Organic Chemistry II, Chem 241, Fall 2010 Web Information: http://www2.chem.umd.edu/groups/davis/courses.html and https://elms.umd.edu/ “Excuse me, but how do I get to Carnegie Hall?” Practice, practice, practice. Overview: Organic chemistry of natural and synthetic compounds is central to our world. Understanding how organic compounds are made and how they react will help you better understand key biochemical and biological processes. Organic chemistry has its own rules and strategies that you may find appealing. I hope this course will interest and challenge you and that the lessons learned will help you later in your studies and in your life. Instructor: Prof. Jeff Davis (Office is CHM 3345, 405-1845, [email protected] ) Lecture: Tues & Thurs, 9:30-10:45 am (Room CHM 1407) Office Hours: Fri, 9:30-10:30 or please make an appointment if you have questions or need help. Discussion and TA: Phong Truong ([email protected]). Phong is a Chemistry graduate student and you should attend his discussion sessions. Discussions are scheduled for Mon and Weds between 12-3 pm. See http://www.testudo.umd.edu/ScheduleOfClasses.html for details. Guided Study Sessions: Guided Study Sessions provide a structured opportunity for students to engage in course material outside of the scheduled class time by arranging weekly peer-led learning and review sessions. Our GSS leader is Nicholas Niazi. Texts: “Organic Chemistry”, 5th edition by Marc Loudon. I encourage you to do as many problems in this text as possible. Other Organic textbooks are available in the library. “Study Guide and Solutions Manual, 5th Edition” by Marc Loudon and Joseph Stowell. Other Resources: Molecular Model Kit- Organic structures and stereochemistry are often visual and hand held models can really help. I strongly recommend getting a model kit. Old Exams are on course website: http://www2.chem.umd.edu/groups/davis/courses.html NHNNONH2NOOHOHOP-OOO-H2NC OHOHNChem 241 Fall 2010 2 Tentative Lecture Schedule* *This schedule is tentative. I don’t lecture right from the book, but you’re responsible for reading not covered in lecture. You should read assigned material BEFORE each lecture.

Tentative Exam Schedule “Hour” exams are held during class period.

There are three 100-pt exams and a 200-pt final. The total points that you earn will determine your grade, based on the following criteria: A 80% or higher (> 400 points) guarantees a grade of A for the course B 70-79% (350-399 points) C 55-69% (275-349 points) D 45-55% (225-274 points) F < 45% (< 225 points) These grades are derived from evaluating scores for 2500+ students who have taken Organic Chemistry with me over 15+ years. Plus/minus grades may be used in some cases. Other Important Information Academic Integrity: This course requires a lot of effort and it is essential that you are honest. It should be your work that is evaluated and the integrity of this course depends on you. You will be asked to sign an honor pledge at each exam. For more information on the University’s Code of Academic Integrity http://www.studenthonorcouncil.umd.edu/whatis.html Exam Make-up: It is University policy to excuse the absences from: illness of the student or a dependent; religious observance; participation in university activities; and compelling circumstances beyond the student's control. If you know of a religious observance or university activity that will preclude you from taking a scheduled exam please let me know by email within 2 weeks of the start of the semester. If you are ill or have some other problem that keeps you from an exam you must notify me within 24 hours of the missed exam. All make-up exams will be given on Fri Dec 10 at 4 pm in room CHM 1407. Exam Re-Grades: All requests for re-grades must be turned in within 1 week of receiving your exam. Steps to take: 1. Assess why you feel you were unfairly graded 2. Write a clear explanation for why you feel a certain problem should be re-graded. 3. Attach your explanation to the front of your exam and give to the Discussion TA. 4. I will then consider your request and may then re-grade the entire exam. Course Evaluations: The online evaluation system, CourseEvalUM, allows you to contribute to our academic programs. Faculty and administrators value this feedback, and students will benefit from having evaluation data for all courses available. CourseEvalUM will be open for students to complete evaluations for Fall 2010 courses between Tuesday, November 30th and Sunday, December 12th. Students can go directly to the website (www.courseevalum.umd.edu) to complete their evaluations.Chem 241 Fall 2010 4 Suggested End-of-Chapter Problems You should try to do ALL of the “in-chapter” problems for any sections of chapters that we cover in lecture. I would also recommend the following problems at the end of the chapters: Unit 1 Chapter 19: 38-42, 44, 45, 47, 49, 50, 60, 61, 64 Chapter 20: 25-27, 36, 37, 45-49, 51 Chapter 21: 31, 32, 34, 38, 39, 44, 52, 55, 56, 59, 61 Chapter 22: 50, 51, 55, 59, 65 b-d, 68, 75, 76, 81, 83, 85 Unit 2 Chapter 15: 38, 39, 43, 52, 53, 55, 69 Chapter 16: 32, 40, 45, 51, 52 Chapter 17: 18, 19, 22-28, 31, 37, 38, 46 Chapter 18: 51 a-c, 59, 64
