CH 455 Exam 2 – Organometallics

In case you need to address questions to my professors, let me know so I can address them. The only source you can use is the one I provided. Note from the professor "Hi Everyone--Please type up answers to the exam that are easy to type and handwrite the rest. You do not need to spend hours drawing mechanisms. It is easier for us to grade if things are typed, so do as much as is possible. The handwritten stuff should be neat and tidy. Question #4 refers to Equation 19.59 on page 903 of your text, not the book chapter that is posted. Remember that the due date is Monday by 5pm. Please submit to Dr. A. If he is not available, have Sarah time-stamp your exam and she can take it."

The style used will be ACS style. Presentation instructions: You must identify a topic covered in the chemical literature within the past six months, obtain at least five additional, peer reviewed resources to support and expand the topic, prepare a scientific poster of the information which you will present on the final day of class. I haven't found trustworthy sources about this article that I found on Wikipedia(https://en.wikipedia.org/wiki/Volkswagen_emissions_scandal). So if you could find trustworthy sources instead, that would be great. However I would like to make a presentation on it, and figure out how they did to trick the test. This is a chemistry Poster Presentation. I ordered like a powerpoint. I will put the poster together. In case you need any further information or have questions, let me know

Scientific Paper

Experiment 1. Friedel Crafts acylation of toluene: 56 (acetylate toluene) 2. 61 with 4-methoxybenzaldehyde 3. followed by reaction with hydroxylamine to make oxime (Luo 2012). 56 & 61 are experiment numbers. I attached photocopies. Luo 2012 is the article reference attached. All sections that are required are described in one of the file uploaded. I will also give the template for the paper, Mac or Windows, after the writer informs me. I have not finished the experiment yet but the writer can start writing the abstract, introduction and experimental sections. It would be great if the writer can let me look at each section right after he finished.
