Sunday, April 3

  • I am not feeling well tonight and have decided to cancel classes and office hours for tomorrow, Monday, April 4. I hope to be well enough to return on Tuesday, and will post an update here late in the day tomorrow.


Friday, March 25 - Sunday, March 27

  • New (updated) powerpoint slides are posted for Chapter 7.
  • I have updated the LECTURE page with a number of additional worksheet answer keys and textbook problem corelations.
  • Sapling Problem Set #6 (Stereochemistry) was posted about a week ago and had an original due date of today. I have extended that due date to Thursday, April 7 (after Spring Break). However, I recommend completing sooner.
  • Two additional Sapling Problem Sets are now posted. We have covered nearly all of the topics you will need to complete Problem Set #7 (due April 10). We will cover the rest of SN2 and SN1 reactions material in the first few lectures following Spring Break. PS #8 will be due April 14. Again, I recommend completeing both of these problems sets earlier than the required due dates.
  • Reminder: Exam #3 will be held on Friday, April 15 (changed from April 13). The exam will be held in 4-148 which is the large lecture hall on the first floor of building 4. I will announce a class meeting in that room sometime earlier that week to ensure that you are familiar with its location.
  • Exam #3 will focus on Chapters 5, 6, & 7 - Stereochemistry, Reaction Energetics, and Substitution Reactions (SN2 & SN1). However, as with most exams from this point forward, acid-base chemistry, molecular structures, conformational analysis, and nomenclature will still be important.
  • Have a great Spring Break!


Friday, March 11

  • Tomorrow is the EYH Conference!
    • If you are signed up as a Go'fer, please plan to attend an informational meeting today starting at 2pm in room 7-106.
    • Tomorrow: Please meet in the lobby of Building 6 (near the bookstore) / 6-102 at 7am!
    • If you cannot help out tomorrow, but have some time today - please come to room 7-106 at 1:30 pm today
    • You will ea.rn a small number of bonus point in the class for your participation.

  • As posted on my calendar, I will not be holding office hours today, but will be adding some extra class-specific office hours / review sessions for next week - please see the calendar!


Wednesday, March 9

  • I am feeling better this afternoon and do expect to return to campus tomorrow for my regular schedule.
  • Reminder: This Saturday is EYH, and we can still use your help as a Go'fer. Please consider participating in the event from ~7am-4pm this Saturday!
  • Given where we are in the lectures, Exam #2 will not be this Friday, and I have decided tentatively to postpone Exam #2 from this Friday to next Friday, March 18. The alternative date to next Friday would be Wednesday, March 16. However, I think the Friday date is preferable due to the lab and the extra time to prepare for the exam. We will make a final determination on the date of the exam this Friday in lecture.

    • Please contact me no later than Friday morning (before the start of lecture) if you have an unavoidable scheduled conflict with a new exam date of March 16 or 18 that you cannot change.

    • Exam #2 will cover the same material as originally planned (lectures on acid-base chemistry through alkane conformational analysis, including Newman projections & chair conformers and problems & reading for Chapters 2-4).

    • We will complete our in-class discussion and practice problems with conformational analysis and have a brief exam review this Friday in lecture.

    • We will begin our discussion of Stereochemistry and Chapter 5 in lecture on Monday, though that information will not be directly covered on Exam 2. (However, please note that the stereochemical analysis and our work with structures may serve as additional review for Exam #2.)
  • I have posted updates to the class calendar and extra practice worksheet answer keys (on the lecture page).
  • I have posted a new Sapling Problem Set (#5) that will be due next Wednesday, March 16 at 9pm.


Tuesday, March 8

  • I am still not feeling well and will not be holding classes or office hours tomorrow, Wednesday, March 9.
  • I do plan to post some updates on the website tomorrow.

    • Please see your email account for the randomly-generated 5-digit code needed to find your grade on the sheet.

  • Exam #1 Answer Key

    • Exam #1 will be returned in lecture next Wednesday; however, you may pick it up from me tomorrow (Feb. 11) during my office hours from 12:15-1:15 pm. I may be in my office at other times as well.

    • Exam #1 covered primarily review material from General Chemistry 1 & 2 - a number of topics that will lead very directly into the material that we will be covering in the coming chapters on organic structures, and relate to most of the topics throughout the course!

    • If you did not do as well on this exam as you would like to in the course, you still have many opportunities for improvement, as there will be three more 100-point exams as well as the 200-point comprehensive final exam.

  • Study Recommendations

    • With the long weekend approaching, I recommend that you revisit the concepts that we have covered in Chapters 1-2 in the text, the lecture, and the practice problems. We will also be completing Chapter 2 next week, and moving on to Chapters 3 & 4. You can also use this opportunity to read ahead and begin working problems assigned in the text.

    • Use the textbook and solutions manual!
      • You may use either the 3rd or 4th edition, and you can order the 3rd edition online pretty cheaply. You should already be using it, so if you've waited, you should have it shipped to you quickly, so that you can stay current with the course.
      • The 4th ed. text and solutions manual will continue to be available for 2-hour library loan.

    • Use molecular models to help with understanding structures. This will become even more important as we move into chapters 3-5.

    • Work the problems on the extra practice worksheets.
      • Check your answers only after you have consulted your notes and/or the text and beleive you have arrived at the correct answer. You will get much more out of them this way than if you look directly to the answer keys!

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.
