Spring 2001 General Chemistry II Lycoming College

Course description - This course is designed to look at ions/molecules in dynamic situations. We will focus on chemical reactions and various measurable parameters associated with reactions (equilibrium constants, energy, rates of reaction….). Applications of these ideas to everyday life will be discussed whenever possible.

Course format

Lectures - MWF, 11:30 – 12:20, HBC G09, Attendance required.

Recitations - Thursday, 7:45 - 8:35 am and 1:00 - 1:50 PM, HBC G40. The primary method for evaluating chemistry students in testing situations is to have them work problems. In recitation we will practice the same sort of problems you will see in testing situations. Attendance expected. I will not take attendance but I might use some of the examples discussed in recitation as exam and quiz questions. I have found, that on the average, students who attend recitation in my courses get an average of one full letter grade higher than those who don’t attend.

Assigned homework - Problems designed to enhance your understanding and prepare you for testing situations. A key will be posted on the web (I'll provide address soon) and outside my office. Homework will not be collected. A large chunk of recitation will be devoted to working these problems.

Laboratory - Here you will experience what chemists actually do. Your labwork will be evaluated as described in the lab. A lab syllabus will be distributed at the first lab session. Make sure and show up with your $5 lab deposit plus $3 copying fee that first week.

Grading scheme

a. The final grade is based on the number of points obtained out of a possible 600 points. I suggest trying to get as many of these points as possible. The points will be distributed as follows:

intro/biography 5 points (01%)

quizzes 60 points (10%)

hour exams 300 points (48%)

final exam (cumulative, standardized)* 100 points (16%)

laboratory 155 points (25%)

total 620 points (100%)

*a higher score on the final exam can be used to replace a lower score from exam 1-3.

b. Assignment of letter grades is based on the following scale: 558 - 620 A, 496 - 557 B, 434 - 495 C, 372 - 433 D, < 371 F.

c. A word about learning chemistry. Studying chemistry is hard work for most people (this is certainly true for me). I would recommend that you work on the lecture material at least one hour per day outside of class for starters. Once you see how things are going this amount can be adjusted as needed (I suggest a significant increase in study time prior to an exam). If you are having trouble make sure and come and see me. I’m easy to talk to and will do whatever I can to help you. A Chem 111 study coordinator is also available (Chris Robbins [she's really smart and I'll bet really helpful too, robchri1 @lycoming.edu]) You will be responsible for all of the material listed on the following schedule for the indicated exams and quizzes. It is not sufficient to learn the material from the lecture alone. You are expected to read and think about the material prior to the lecture. I also suggest you work problems, LOTS of problems. We must necessarily cover a large amount of material so our pace must be geared towards those who are ready to learn. The hour exams will be somewhat cumulative in the sense that we need to know the earlier material to comprehend the latter.

Policy on attendance

Attendance at quizzes and exams is mandatory. No makeups will be administered. If I am made aware of the absence beforehand and I deem the reason for the absence to be legitimate, later tests/quizzes will be averaged and used for the earlier missed exam or quiz. Each documented, unexcused lecture absence beyond the first two will cost you one point from your total (be there or be square).

1. Name and what you like to be called; Chriss McDonald, you may call me Chriss, Dr. McD, or Dr. McDonald.

2. Major (and note whether it is intended or actually declared); As an undergrad (late 70’s) I was actually a medical

technology major.

3. Minor (and note whether it is intended or actually declared); An unofficial one in history.

4. Fr., So., Jr., Sr.; Very senior.

5. 4 digit code for the posting of grades; N/A.

6. Tell me two interesting/funny things about yourself; I'm still looking for a place to use my 4 years of college hoops eligibility. I believe the earth to be wildly overpopulated by human beings

7. Tell me about your background in chemistry. I thought chemistry was merely OK until I got to organic, went bonkers over that. Went to grad school at Miami of Ohio in synthetic organic chemistry. Still learning lots of cool stuff about

organic chemistry. I’m interested primarily in the development of new synthetic methods. Specifically the

development of new strategies for carbon – carbon bond formation.

8. A recent photo of yourself (2 point bonus); see below (me and my NMR magnet!)
