For those in the lecture only, if you can stop by office hours after class on Tuesday, that would be best. If not, perhaps we can make an appointment for a different time on Tuesday. Please email me if you would like to make an appointment.
- I will be making one of the following adjustments to your course grade at the end of the semester. It will be whichever results in the better grade:
- Your lowest exam score will be replaced with the average of your lowest exam percentage and your final exam percentage.
- Your lowest exam score will be replaced with the average of the percentages on all three lecture exams and the final exam.
- The above method of applying a grade adjustment (curve) will have you only competing against your own previous scores and not against your classmates.

- CHEM 235 (Lecture) Course Materials:
- Required textbook: Solomons & Fryle, ORGANIC CHEMISTRY, 9th ed.
- Highly recommended: Study Guide & Solutions Manual for ORGANIC CHEMISTRY, 9th ed.
- Notes on the textbook and study guide:
- The textbook recently went into a 10th edition. If you do not already have the 9th ed., you may be able to find it inexpensively online.
- The 8th ed. of the textbook is also acceptable. However, textbook problem assignments are given from the 9th ed. You should see the conversion guide on the lecture page for corresponding 8th ed. problem numbers. If you use the 8th ed., purchase the corresponding Study Guide and Solutions Manual.
- Highly recommended: Student Molecular Model Kit
- CHEM 238 (Lab) Course Materials:
- Please see the CHEM 238 Course Syllabus for a complete listing.
- Required Textbook: Introduction to Organic Laboratory Techniques: A Microscale Approach, 4th edition by Pavia, Lampman, Kriz, and Engel.
- The 3rd edition of this lab textbook can be used, but requires significant correlation of experiments and techniques on your part.
- Getting started:
- I recommend that you review the textbook sections in Chaps. 6-10 relating to CHEM 234 topics and work problems assigned from those sections. You can find these readings on the LECTURE page.
- Begin reading / reviewing Chapter 11 and doing the problems assigned for that chapter.
- Science Lecture Series: A number of outside lectures will be presented at Skyline (and other instituions) throughout the semester. You will be required to attend approximately 3 lectures for credit - 2 for lecture, 1 for lab. Extra credit for attendance at additional lectures may be offered.
- Academic integrity will be be taken very seriously in the course. All students are expected to act with respect and honor codes of student conduct. This topic will be addressed in detail in the first week of classes in lecture and in lab. Please scroll down on this page to read Skyline College academic honesty information.
- Please visit the links to the left for other information related to the course.
- Reading & book problem assignments and other important items are posted.
- Check back regularly - there will be frequent updates.
Academic Integrity
- Academic integrity is an important issue in all academic settings, and will be taken very seriously by the instructor of this course, and the college generally.
- I recognize that most students conduct themselves with honesty and integrity. I also recognize that the actions of a few dishonest students and the impact of those actions on the academic process necessitate a frank and ongoing discussion of this issue.
- Please review the student handbook information on academic
integrity at the following link: http://www.skylinecollege.edu/pdf/campuslife/studenthandbook/PoliciesandProcedures.pdf
