READING ASSIGNMENT
undefined
Please read the following material in “Laboratory Techniques in Organic Chemistry” (4th ed.) by Mohrig, et al:
undefined
- Chapter 9 – Filtration (Sections 9.1-9.2)
- Chapter 18 – Thin Layer Chromatography (Sections 18.1-18.6, 18.9)
If you don’t have the textbook, you can use the Chemistry Libretexts website and look for thin layer chromatography.
, please look at the papers that I will attach ,
PLEASE watch this video for the Conclusion part for this lab it is very important

Theory and Conclusions for the experiment
This section should indicate how your results related to the purpose of the experiment and what can be interpreted from your results.This section should indicate how your results prove the theory behind the reaction or procedure.Most of the information on the theory section can be found in your lecture book or in the prereading section of the lab experiment as well as the reading sections from the textbook, and research using the ACC library particularly AccessScience, Kirk-Othmer Encyclopedia of Chemical Technology, Van Nostrand’s Scientific Encylopedia, and Gale ebooks. This section will be graded the hardest and rambling results in grade deduction.You should be able to make your point in 3 to 5 pages
