Course Description
and Objectives:
Chemistry 242 is a course that will build on the foundation that was established in CHM 241. The course will begin with the study of free radical reactions and alcohols and then focus on structure elucidation using mass spectrometry. Visit my LINKS page for good spectroscopy sites. We will then look at conjugated p systems including pericyclic reactions and aromatic (benzene-type) chemistry. The course will continue with examination of structure, preparation, and reactivity of oxygen- and nitrogen-containing functional groups within molecules. The approach used will incorporate orbital analysis (structure), electron distribution and flow (mechanism), reactions, and ultimately synthesis.
The amount of material to be covered is quite large and it will be presented in 15 sessions, thus it is necessary that you keep up with the course lecture to lecture. This is most readily accomplished by reading the appropriate chapter prior to attending class and doing the assigned problems. This way, the material covered in class will seem somewhat familiar (what a great feeling) and will hopefully clarify any questions you might have. Do not hesitate to ask questions in class, after class or during any office hour on line or at La Salle University. Use of the study guide is helpful, but only if you first attempt the problems on your own. We will follow the attached schedule as close as possible. If we begin to deviate substantially, a new schedule will be produced.
Examinations, Quizzes
& Chapter Coverage:
Your grade will be determined by your performance on two examinations, three quizzes and a cumulative final examination. Exams will take place from 7:40-9:10, (regular lecture from 6:30-7:30). Quizzes will take place from 8:10-9:00 (regular lecture from 6:30-8:00). The exam and quiz schedule with probable chapter coverage follows:
| Quiz 1 | due February 12 | CH 10-11 |
| Exam I | March 4 | CH 10-14 |
| Quiz 2 | April 1 | CH 15,16 |
| Exam II | April 22 | CH 15-18 |
| Quiz 3 | due May 6 | CH 19-20 |
Strategy:
As is evident by the ambitious schedule and the fact that we have 14 sessions together, it is important that you keep pace with this course. It is well documented that attempting to cram three weeks of material into a day and a half prior to an exam is an unsuccessful method to studying in this course. I would advise that you print out the Powerpoint slides prior to coming to class. They will be posted by Tuesday afternoon every week (and likely eartlier). Rewriting one’s notes after each lecture is an effective way to reinforce the lecture material and it typically brings questions to the surface. In a three-hour class this will be particularly important. Do all of the suggested problems and practice sheets. Use your Teaching Assistants as well. Attendance will not be taken regularly, but consistent lecture attendance is strongly urged and necessary since examinations reflect my emphasis in class (and absences will be noticed).
Our anticipated schedule for the semester is ambitious. Please make a note of the dates of quizzes and exams.
Adobe Acrobat Reader is needed in order to access handouts.
