CHEM 146A

Advanced Organic Lab for Chemistry Majors

146A Intro to Lab Manual (p 1-14)

INTRODUCTORY ANNOUNCEMENTS

The lab manual is available in the bookstore as of 9/21. Do not purchase the lab manual unless you are enrolled (no refunds) and do not attend lab if you are on the wait-list. The first lab meeting is Tuesday, October 3rd at 1:30pm and is mandatory. Dress appropriately for every lab even when an experiment will not be performed. Students not present by 1:45pm will be dropped from the class.

The beginning of the lab manual (syllabus, intro, schedule, etc.) is posted above and may be updated as the course progresses. Read up to and including Exp 1.1 carefully before the first class meeting. The schedule is subject to change as the class structure is fluid. Please check this website on at least a weekly basis for further updates throughout the quarter.

You will need a new lab notebook – any lined and bound notebook without duplicate pages will do. There is no specific text assigned to the class, but you should already have an experimental organic chemistry textbook from the 8 series (Mohrig or Palleros). Any experimental ochem text should be suitable for this course if it contains chapters on extraction, chromatography, NMR, and IR. Read the text sections on column chromatography and liquid-liquid extraction (acid-base extraction) before the first lab meeting. Wait until you get the lab manual to prepare your notebook for Experiments 1.1 and 1.2.

NMR Predictor! Use this to find the expected chemical shifts of your unknown and/or compare to the values calculated from the textbook’s correlation tables. Don’t rely too much on the expected multiplicity as this site incorporates longer range coupling than we talk about in class.
