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...

Cumulative Final Exam Review Orgo II Questions and Answers Rated A+ 1. Carboxylic acids react with nucleophiles through what type of mechanism? Answer: Addition followed by elimination Addition followed by elimination Explanation: Carboxylic acids typically undergo nucleophilic acyl substitution. In this mechanism, the nucleophile first adds to the carbonyl carbon of the carboxylic acid (addition), forming a tetrahedral intermediate. This is followed by the elimination of a leaving group...
