Announcements & Important Course Information

December 18

  • Thank you for a very rewarding semester. I enjoyed working with your class very much and wish you all the best for the future!
  • Final grades postings:
    • CHEM 235
    • CHEM 238
      • Note on the BONUS points: For those of you in lecture and lab, I applied first to the lecture and then to the lab. Because the bonus points did not make a difference for the lecture for anyone, I applied the maximum possible to the lab, and left the rest on the lecture.

Friday, October 4

  • I am not feeling well, and will be cancelling class for Friday, October 4.
  • See the LECTURE page for the Orbitals & Thermodynamics worksheet answers and the Reactions 3 worksheet & answer key posted today.
  • Exam #2 - Review Guide - Fall 2013

    • This guide covers most of the topics to be covered on Exam #2, but may not be an exhaustive list. Be sure to review the course notes and reading assignments as well.

    • Many questions from the previous semester Exams #1 & #2 will be good practice for this exam.
      • Focus on the previous semster Exam #1 questions that were not focused on for the current semester Exam #1. However, all of the retrosynthesis questions will be good practice, as this is a cumulative topic.
      • Questions on the previous semester Exam #2's relating to Electrophilic Aromatic Substitution and determining if a species is aromatic will be NOT covered on this semester's Exam 2.

    • Please take note the radical reactions presented in the notes outlines and the text. They are a review of topics from the first semester, and could be presented on the exam, though they were not covered at length in lecture. The mechanism of these specific radical reactions will not be the focus of questions, but rather the likely products to form in any radical reaction of an allylic or other conjugated radical based on their relative stabilities - a concept central to the current material.
  • You should currently be reading and working problems from Chapter 13 in the textbook.
  • Reminder: PS #4 is due by 5pm on Saturday, October 5. There will not be another problem set due before the exam, but the newly posted worksheet will be good additional practice, and is highly recommended.


September 28

  • As announced, Exam #2 will be postponed to the following week. Based on the feedback I received and the schedule for the course, the new exam date will be Wednesday, October 9 in lecture. I have updated this on the calendar.
  • The Sapling PS #4 will now be due on Saturday, October 5 by 5pm.
  • CHEM 238: I have updated the course calendar and the Experiment #27 handout is now posted on the LAB page.

  • Review & 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. Extra Practice Worksheets titled Reactions will also be good review. You can find these assignments on the LECTURE page from CHEM 234 for Spring 2013.
    • You may also want to review earlier material related to bonding, nomenclature, stereochemistry, and related topics if it has been some time since you completed the first semester course. Readings and book problems as well as additional worksheets are also available on the CHEM 234 lecture page.
    • Begin reading / reviewing Chapter 11 and doing the problems assigned for that chapter.

  • 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.
