Course Description:  CHEM 220, Organic Chemistry I, is an introduction to the study of the chemistry of carbon compounds.  The course covers the chemistry of alkenes and alkynes, the substitution and elimination chemistry of alkyl halides, the theory and applications of infrared spectroscopy, and the strategies of organic synthesis.  The laboratory portion of the course will introduce the student to a variety of techniques for the synthesis, purification, and analysis of organic compounds. 

 

Text and Materials:

• "Organic Chemistry" 6th Edition, John McMurry, Brooks Cole Publishers.

• "Study Guide and Solutions Manual for Organic Chemistry, John McMurry (optional).

• Molecular Model Set for Organic Chemistry (Lehman).  These can be shared.

• Bound laboratory notebook (Freeman).

• CHEM 220-221 lab manual.

• Safety glasses or goggles (sold by Chemistry Club).

• Calculator with logarithmic and exponential functions.

 

Materials in Chemistry Reading Room:  Copies of several organic chemistry texts are available in the reading room (217 Heim Bldg.).  If you are not satisfied with McMurry’s treatment of a topic, feel free to consult one of the other textbooks--you may just find one you like.  These texts are excellent sources of extra practice problems (solutions manuals are available for several of the texts as well).

 

 

Grading Criteria:                    Intro Assignment                           5 points        

Quizzes                                     105 points        

                                                Exams                                      300 points

                                                Final                                         125 points        

                                                                                                660 points        

 

Final letter grades will be assigned as follows: >90% A, 80-90% B, 70-80% C, 60-70% D, <60% F.  The ranges given include "+" and "-" grades.  Be aware that you must pass both the lecture and laboratory to receive a passing grade for the course.

 

Exams:  There are three in-class exams on the following dates:  Friday, September 26; Friday, October 24; and Monday, November 24.  The final exam will be administered on the day and time assigned by the registrar.

 

Quizzes:  Quizzes are an incentive to stay current with the course.  They provide you with a means of evaluating your progress and allow you to identify any potential "trouble spots" before the exam.  The lowest quiz grade will be dropped.


 

Assignments From the Text:  The course outline (on the next page) lists reading assignments for each class.  I suggest you skim the assignment before class and then read it again more thoroughly afterwards.  I highly recommend taking notes on the reading.  Detailed chapter outlines and problems for each reading assignment will be distributed throughout the semester.  Although the homework problems will not be collected, you should complete them before the next class period to insure that you understand the material.  Lectures, quizzes, and in-class exercises are prepared with the expectation that you have read and understand the assigned material and have completed the problems.

 

Review Session:  The evening help session is an informal workshop where you will have the opportunity to work problems individually or in groups, ask questions and review lecture material.

 

Extra Credit:  There are two ways to earn extra credit – by attending Chemistry Colloquium and by taking advantage of bonus point opportunities. 

Colloquium Bonus: Extra credit points can be earned by attending departmental colloquia (3 per colloquium).  If you are unable to attend some or all of the colloquia, you may also earn colloquium bonus by writing a brief research paper on an organic chemistry-related topic (up to 10 points).  The instructor must approve the topic and will provide additional details regarding the requirements for the paper.  Extra credit papers will not be accepted after the final exam. Colloquium bonus is limited to 15 points. 

Bonus Points:  You can earn additional bonus points by answering bonus questions that may appear on exams.  Other bonus point opportunities may arise throughout the semester, normally in the form of homework assignments.  These are counted above and beyond the 15-point cap for colloquium bonus.

 

General Comments: 

Attendance:  Attendance is mandatory.  Three absences (regardless of the reason) are permitted; all additional absences will be penalized (3 points per absence).  Missed quizzes, exams and laboratory meetings cannot be made-up unless the absence has prior approval from me and can be documented (for example, by a note from student health services or the Dean).  A missed quiz or exam will be recorded as a grade of zero.  Students who miss a mid-semester exam or quiz, with prior approval, will be given a single, cumulative make-up exam or quiz at the end of the semester. 

 

Study Suggestions:  Perhaps the best advice I can give you on how to succeed in this course is:  Don't get behind!  We cover a lot of material in this class and cramming for a night or two before an exam simply won't work.  Furthermore, each section builds upon the material covered in the previous chapters and to succeed in this course you need to be fluent with one chapter before moving on to the next.  Just like learning a foreign language or becoming proficient at a sport, you need to practice a bit each day.  Review your class notes, read the text, discuss the material with your classmates, quiz yourself, and most importantly:  work lots of problems.  And remember, my job is to help you learn organic chemistry--if you have questions, if you are not sure how to approach a certain type of problem, or if a concept is still a little fuzzy, ask me about it!

 

Useful resources on the web:

The on-line catalogs and databases are good sources of information for your lab reports.  We'll talk more about them at the first lab meeting.  On most of these sites, you can search for a chemical by its name (whole or partial) or by its formula.  Chemical listings normally include the name of the compound, common synonyms, formula, molecular weight, density, boiling point, melting point and a link to the MSDS (material safety data sheet) information.

                                                Aldrich Catalog                         www.sigmaaldrich.com

                                                 Yahoo                                      www.yahoo.com/Science/Chemistry

There are numerous sites that list other chemistry-oriented web sites and Yahoo is one of them.  Yahoo lists web sites according to content (atmospheric chemistry, biochemistry, chemical and biological weapons, chemical constants, organic chemistry, periodic tables, etc.).  Yahoo also has MSDS information.

Exam Week:

 

 

The final exam will be given on the date and time assigned by the registrar.  No exceptions!

 


 

Laboratory:  It is imperative that you come to the lab fully prepared.  Careful planning and preparation before you arrive at the lab will allow you to complete your experiments in an efficient and safe manner.  It is your responsibility to read and understand the lab procedure before you arrive at prelab.  Missing or arriving late to prelab will result in a reduced lab grade (up to 5 points per violation) and/or dismissal from the lab.

 

The laboratory grade is worth a total of 125 points and is comprised of nine lab write-ups (90 points total), three lab quizzes (30 points), and a lab technique evaluation (5 points).  The lab technique grade is assigned based on the following criteria:  preparation for lab, safety in the laboratory, ability to work efficiently in the laboratory, ability to successfully complete experiments, and laboratory hygiene.

 

Lab Safety:  Unsafe behavior in the lab will not be tolerated and violations will be penalized.  Repeated violations during a class may result in a zero for that lab.  Keep in mind that lab safety includes laboratory hygiene.  In the event that common areas are left dirty, (rotovaps, balances, melting point apparati, reagent hood) points may be deducted from the entire lab section.  If you have any questions regarding lab safety, please do not hesitate to ask.
