Synthesis of Salicylic Acid Experiment Questions

Heating Under Reflux: Synthesis of Salicylic Acid (from Lehman text, 2nd edition)

* Note: Read the entire lab experiment provided in the Week 14 Module on Canvas (pages 6169) to obtain a more complete understanding of the experiment. If you performed the experiment in person, please use your own data and results as much as possible to answer the following questions. Any results that were not obtained in person should be obtained from the videos provided in the Week 14 Module.

Lab Report Questions:

1. a) Determine the theoretical yield of the product (salicylic acid) and show all of your calculations. (Note: This is done just like you learned in general chemistry starting with the mass of the limiting reagent and converting to mass of the product).

  1. Provide the final mass of product after recrystallization (show calculation).
  1. Determine the percent yield of product.
  1. Provide the melting point range of the product.
  1. What is the purpose of using a reflux condenser in organic reactions?
  1. Provide answers to the following Exercises from page 69 of the lab experiment handout.

Exercise 2a)

Exercise 2b) (Note: You will need to draw structures for the organic compounds involved in the reaction)

Exercise 5a)

Exercise 5b)

Exercise 6)
