Organic chemistry homework help
2. Use this article “Synthesis of Dimethyl Derivatives of Imidazolinone Herbicides: Their Use in Efficient Gas Chromatographic Methods for the Determination of These Herbicides” to creat 8-10 ppt slides and write explanation and analysis for each slide.
143C Spectroscopic Elucidation Project
OBJECTIVE:
Students will be tasked to create a presentation based on a publication describing the structural elucidation of an organic molecule. This project will demonstrate the student’s ability to interpret the data and critically analyze the elucidation methods. This project will also demonstrate the student’s proficiency in science communication.
SCOPE:
Each student will be given the freedom to explore the literature and present an elucidation of their choice (with TA or instructor approval). The publication must describe a structural elucidation based on, at minimum, mass spectrometry (MS), nuclear magnetic resonance (NMR, 13C and 1H) spectroscopy, and one other spectroscopic analytical method (i.e. IR, 2D- NMR, UV-Visible Spectroscopy, etc.)
Students will prepare a critical analysis (not just a description) of the elucidation methods detailed in the publication for a verbal Powerpoint presentation. Presentations will be recorded on Zoom using Cindy Tran’s (143B Lab Staff) account, which will be automatically be uploaded onto Canvas. You will need to sign up for a designated recording time slot by November 18-19.
The presentation must meet the following criteria:
- Presentation time limit: 5-10 minutes
- Presentation slide limit: 8-10 slides
- Presentation of data AND rationalization/justification of why the data are important: you will focus on one piece of spectral data that you believe (not necessarily what the authors say) was key to assigning the structure and provide your justification why these data were critical in assigning the structure
- Also, you will need to include your assessment of the of the elucidation. Propose other methods that could have been done and what information they would hypothetically provide.
SUBMISSION DATES
- October 26-27: Journal Article Submissions due
- October 28-29: Article Approved, Draft Outline due
- November 18-19: Presentation Draft Slides due, Recording Date Selection due
- November 22-23: Project Slides due
- December 7-8: Presentations recorded
The following is an outline of the presentation format:
ONE SLIDE ONLY
Title slide: Analysis of “The structural elucidation of …..” by Joey Bag of donuts, et al; J. of
Irreproducible results, 2000, 23, 100-101. By: Student Name
*NOTE: your citations MUST be in ACS citation format.
ONE SLIDE ONLY
Introduction: Where the product was isolated? How was it isolated? How was it purified? What was the purity level and method used for the evaluation of percent purity?
2 SLIDES
Present critical data related to structural determination with explanations in a logical order.
2-3 SLIDES
Student analysis of data including the key data that were crucial for the elucidation (without
which the elucidation would not be as good/possible)…be specific; not just “NMR” but “the
2D NMR showing the stereochemistry of….”
1-2 SLIDES
Student evaluation/critique of the quality of the structure: 99+% certain, etc. with justification. What other data could be obtained to firm up the structure?
ONE SLIDE ONLY
