Lab Activity - Interpretation of Physical and Chemical D

After completing this lab activity, you should be able to,
Carry out a research-based experiments and identify unknown organic compounds.
Identify the common organic compounds’ functional groups and determine the structure of an unknown compound
using UV/Vis, IR, Mass, and NMR spectroscopes.
Use Material Safety Data Sheets (MSDS) to obtain information such as molecular formula, physical properties, ha and disposal procedures for chemicals used in each experiment.
Prepare and maintain a laboratory notebook, including a write-up of each experiment that details the purpose, che
equations, calculation of theoretical yield, percent yield, and record of experimental observations.
Write clear, concise, scientific laboratory reports using American Chemical Society style for each experiment.
Use critical analysis skills to interpret data and draw conclusions.
DETAILED INSTRUCTIONS FOR LAB ACTIVITY COMPLETION:
This is a research-based lab. This means that you conduct research online or using the library to identify the unkn
compound or missing values from the given information, and then produce a lab report. The lab report should des
how you arrived at your conclusions. Therefore, this lab report may look as follows:
Title: Title of this experiment – There should only be one title for the experiment ("Interpretation of Physical and
Chemical Data").
Method: In this section, you explain the given physical or chemical data for each question (you may number them
according to the question number), the instruments used, and their purpose. If the same instrument has been use
twice, you need to explain that instrument only once. Then, explain the method you would follow to answer each
question.
Analysis: In this section, you show your analysis of the given information for each question.
Results: In this section, you will show your results for each question.
Discussion: In this section, you may discuss the rationale for your solution and what other information would have
your findings easier.
Conclusion: In this section, you detail your results and explain with what percentage of certainty you could confirm
results.
Remember to add any relevant references following the APA format.
You should upload the lab report to the relevant assignment box.
