I have read all of the assignments that were turned in and I will be returning them in class on Monday. In addition to the comments that my graders and I have put on your assignments, there are two additional things that I want to bring to your attention:
- To make grading go more quickly, my two graders and I have used a set of two- and three-letter codes. These were also used last year and you can find an explanation of these codes at this post from September 15, 2008.
- I made a mistake when writing my answers for HW #1. When I read Loudon 1.39 (problem #6), I mistakenly substituted HCl and HF for CH3Cl and CH3F, respectively. The central point of my answer, Cl makes longer bonds than F, still applies, but my comments about treating atoms as charged particles need to be modified. Come see me if you would like to discuss this or any other matter pertaining to the course.
