Project Overview
Click here to download a copy of the Lab Notebook Template for Project 2.
Laboratory work for Project 2 will be completed in pairs. Each assignment (e.g., workshops, quizzes, notebooks) must be completed individually.
Project 2 will introduce you to several basic concepts related to performing chemical reactions in the organic chemistry lab. The Reaction Preparation Workshop will help you prepare your lab notebook by refreshing your skills in stoichiometry and introducing you to certain skills critical to the experiment. Two other workshops (Gas Chromatography and Mass Spectrometry) will familiarize you with additional techniques used to analyze the purity and identity of a sample – in this case, the reaction product.
Keep in mind that whenever a chemist performs a chemical reaction, there are at least three measures of success to consider:
1. What is the identity (i.e., structure) of the product(s)?
2. What is the quantity of product generated (by mass and percent yield)?
3. How pure is the isolated product?
Your overarching objective is to analyze the data gathered in Project 2 to make a logical argument regarding these three measures of success for your Project.
Learning Objectives
• Plan and execute a simple chemical reaction involving an organic substrate
• Perform TLC to determine the progress of a chemical reaction
• Perform a liquid-liquid extraction as part of a reaction “workup”
• Obtain and analyze a mass spectrum
• Obtain and analyze a gas chromatogram
• Obtain and analyze an infrared spectrum
• Combine multiple lines of evidence (e.g., a mass spectrum, IR spectrum, gas chromatogram, and measured mass) to produce a coherent argument regarding the outcome of a chemical reaction
