In order to answer them, I first need help with filling out the GC data analysis table and its analysis section. This consists of labeling on the spectrum and doing calculations. I provided all the necessary information.
Just to note for the question, “1. Print the spectrum for your assigned base only”. The base I used is isobutoxide which is labeled on the top. It is also labeled “308-001 bench 5.” This is the one that needs to be labeled and clearly show the compound structure that corresponds to each peak.

Reflection Task Sections 1-3 (10 marks)

Now that you have completed the 3 sections of your Portfolio part 3, prepare a 150-200 word reflection piece on the importance and significance of this learning to your life in general and potentially even your future career.
Base your reflection on the resources provided.
• Section 1- Glucose in Drinks
• Section 2- pH in biological systems
• Section 3- Gases around us: ‘The Chemistry of Airbags’ article and the reading attached to the calculation you chose.
• Questions and related readings embedded in Sections 1-3 of your Portfolio Part 3.

This reflection can be in the form of a short video, blog, podcast or any other means you are comfortable with to communicate the information to us.

To help you out, answer the following questions in your reflection:
1. What have you learned from the readings and calculations provided in Section 1 to Section 3 that you did not know before?
2. Now that you have done the calculations and read the WHO information in Section 1, have you learned new things about sugars you did not know before. How much more aware are you about sugars in our diet? Think about the calculations you completed in Section 1 and the drink you analysed, elaborate on your answer to Task 3 in Section 1.
3. What in your opinion is the importance of being able carry out calculations about acids and bases for health professionals?
4. How does being able to carry out calculations involving gases enhance our lives when looking at the three readings provided in Section 3?

Remember: Your reflection should show your analysis of the topics covered with a relation to real life and/or the health profession that you are hoping to move into. For example, you may wish to use the sugary drink you focused on in Section 1 as a lead in to discuss the amount of sugar in an average diet and any long-term health implications.

Power point presentation about one of the following analytical instrument (HPLC, GG, AAS, MS, ICP or IR) the information should be inferred from one article published in scientific journal.
(PowerPoints and summery paper). You must orginze the slides. and you must work on one article published in scientific journal. Keep in your mind the first slide which has the the tittle and my name will not be counted from 12 slides. You must take the important and qualified of articles and be inserted to PowerPoints slides. In additions, I need 4 page summary paper for the article

The project is very similar to other previous lab assignments. It is to write your own individual final project in the lab report format. The only difference between the previous lab assignments and the final project is that you are the chemist who makes your own project for your theoretical dry lab experiment. Literally, you are the organic chemist who decides everything in your own report in the same format that we used for the previous lab reports. You need to do this project by yourself without my help. It is all up to you.
In this project, you can choose any compounds to isolate from any fruit or any vegetable (except carrot).
Examples) isolation of lycopene from tomato, isolation of beta-carotene from spinach, isolation of caffeine from tea leaves or coffee beans, isolation of capsaicin from pepper, isolation of limonene from citrus fruits (lime, orange, lemon, etc.) or anything else that you want to isolate in your imaginary theoretical dry lab.
Lab Format (the same lab format as the previous lab reports)
Additionally, the report needs to be single-spaced and longer than at least 4pages. You may need to put a number of references to support your reasoning for your own procedure and arguments in the discussion. (However, use the online videos or pieces of literature as only supplementary information. You need to make your own procedure or make the modified version of the procedure.)
Most importantly, in the discussion, you need to explain why you use certain methods to isolate the compounds from the fruits in each step of the procedure. (among recrystallization, distillation, extraction, column chromatography, TLC or any other organic chemical methods) You do not have to do the percent yield since this is the imaginary theoretical dry lab.
Purpose (why we did the exp.)
Chemical Structure (make sure to put the reference. You can draw your own structure with free software (any chemical structure drawing software is ok. However, put the name of the software below the structures)
Safety Information/Physical Data (physical properties of compounds)
Procedure (Your own paragraph form (past participle and passive voice))
Clean-Up (how to clean up the wastes)
Observational Data Presentation
Color of the isolated compound
Pictures or Drawings of TLC plates with captions
Rf calculation work
Discussion (in PARAGRAPH FORM)
What are the similarity and the difference between column chromatography (CCG) and TLC? Why acetone? Why dichloromethane and hexane? Why sodium sulfate? The polarity of powdered alumina? Why hexane again? Use the tables on pp 187 and pp188 to explain how the compound (in the mixture in carrot) can be separated.
What is TLC again? What are stationary/mobile phases in TLC at this time? The surface of the silica gel has what groups? Is it polar or non-polar? How polar is beta-carotene and what color? How does polarity affect the Rf values of the compounds? Are there differences in data (between two repeated samples)?
Why the Rf value for each spot would be the same? why desorbing power again in this paper? What is the ratio between the ethyl acetate and hexane at this time? Any possible error?
References (ACS format)
Side reaction: N/A
Theoretical yield: N/A
Mechanisms: N/A
Analysis of TLC/IR/NMR: show your TLC data again with Rf values.

For each question, give the ACS Olympiad Year and Question Number and copy down the entire question including all possible answers (A) – (D).
Give the correct answer and show work for how you arrived at the correct answer. You will lose points if you only show the correct answer without any explanation.
