What This Document Is
This document is a post-lab report detailing an experiment in Organic Chemistry II focused on the Friedel-Crafts acylation of ferrocene. It presents the procedures, data, and analysis from a practical application of electrophilic aromatic substitution. The report explores the reaction of ferrocene with an acyl halide, specifically using acetic anhydride, catalyzed by a Lewis acid.
Why This Document Matters
This report is essential for students enrolled in Organic Chemistry II Lab (CHM 2211L) at Florida State University. It serves as a record of experimental work, demonstrating understanding of reaction mechanisms, spectroscopic analysis (TLC, 1H NMR), and quantitative analysis (yield calculation). It’s used to assess a student’s ability to perform organic synthesis, analyze results, and draw conclusions based on experimental evidence. Understanding Friedel-Crafts acylation is foundational for further study in organic chemistry, particularly in aromatic chemistry and reaction mechanisms.
Common Limitations or Challenges
This report focuses on a *specific* experiment. It does not provide a comprehensive overview of Friedel-Crafts reactions in general, nor does it cover all possible acylating agents or catalysts. It also assumes prior knowledge of organic chemistry principles, including aromaticity, reaction mechanisms, and spectroscopic techniques. The report details *one* instance of the reaction and doesn’t explore variations or troubleshooting.
What This Document Provides
The full report includes: a detailed introduction to ferrocene and Friedel-Crafts acylation, the reaction mechanism involved, a list of chemicals used with their properties and hazards, the experimental procedure followed, data obtained from Thin Layer Chromatography (TLC), 1H Nuclear Magnetic Resonance (NMR) spectroscopy, and yield calculations (including actual, theoretical, and percentage yield). It also presents the melting point of the crude product and compares it to literature values, alongside a discussion of the results and potential sources of error. This preview does *not* include the full experimental procedure, spectroscopic data, or detailed discussion sections – it only provides an overview of the report’s scope and content.
