    Welcome to the spring semester of Chem 12AL, Organic Chemistry Laboratory. This initial lecture is an introduction to the myself and the course. We covered the course syllabus, required materials, different locations (this website, Canvas) where course materials will be stored and linked, and much more. There were no notes taken for this lecture.

    While we are online for these four weeks it seems best if we deal with topics outside of the actual lab experiments. Today we focused on the laboratory notebook and a starting look at formal reports. I'm sorry, this is a rather dry session. It's not easy to make laboratory notebooks and formal reports exciting. It is critically important stuff considering two-thirds of what a chemist does is communicate in either verbal or written modes.

    Today we took a look at formal reports and the formal report rubric. I presented two professional publications that are advanced in chemistry, but extremely well written. Read them for the writing and the formatting. Additionally we looked at a sample student report and used the formal report rubric to score it.

    This lecture is on the Global Harmonized System (GHS) for communication of chemical hazards. The GHS is a set of rules that standardize the information that is contained on chemical labels and Safety Data Sheets (SDS) such that regardless of manufacturer or country of origin, as long as the country abides by the GHS, all chemicals should have the same information available - and identical chemicals will have identical information regardless of point of origin. We look at the labeling requirements and importantly how to read and interpret them. We also look at the SDS and the most important ares of the SDS to concentrate on for relavent for working with that substance in the laboratory.

    While we talked about labeling and the GHS system last week, this week we take a look at individual sample labeling and waste labeling. This lecture is about 90 min long.

    There was no class meeting today as I had a chemical waste pickup at Cabrillo Aptos campus.

    We used today's lab session to support lecture by taking a closer look at the skill required to master resonance. In this lecture we look at formal charge and lone pairs in bond line formulas, the interpretation of the bond line formulas. This part is critical to understanding bond line formulas so that when we move into resonance less mistakes will be made. We then looked at good and bad resonance arrows and trying to recognize each in different situations. Finally we took a look at resonance with both positive and negative charges.

    We had a shorter session today. The goal of the session today was to get ready for our first face-2-face meeting on Wednesday of next week. We covered expectations for that first day, locker check-in, visual inspection of glassware, how to use some of the glassware, and finally calibration of pipets.
