1. (3 points) In this experiment, what solvent was placed in the test tube? 2. (4 points) Why was warming data used for estimating the freezing/melting point of the cyclohexane? 3. (3 points) In this experiment, how long was the melting process observed? 1. cyclohexane 2. Solids tend to supercool, which gives false data. So, warming data gives a better approximation of freezing/melting point. 3. 8 minutes

Title: Organic Synthesis Purpose: In this lab, three carbon based organic compounds were synthesized to determine their true purity. The experiments were done to learn about how to use these compounds’ melting points and infrared spectroscopy to determine their percent yield. Procedure: Experiment 1: Making Acetylsalicylic Acid (aspirin) 1. Obtain a flask. 2. Weigh 2 grams of salicylic acid. 3. Put the 2 grams of salicylic acid into the flask. 4. Put 5 mL of acetic anhydride into a gr...
